20100215412 | TRANSFER APPARATUS, IMAGE FORMING APPARATUS, AND IMAGE FORMING METHOD - A transfer apparatus includes an image bearing unit, a transfer member and a bias generator. The image bearing unit is configured and arranged to bear an image. The transfer member is arranged with respect to the image bearing unit to form a nip portion therebetween. The transfer member includes a substrate and an elastic member. The substrate has a recessed portion with an opening width of the recessed portion being larger than a width of the nip portion as measured in a moving direction of the transfer member. The elastic member is fixed in the recessed portion and wound around the substrate. The elastic member has a volume resistivity of 1×10 | 08-26-2010 |
20110008080 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - An image forming apparatus includes a latent image bearing unit, an exposure unit, a developing unit, a transfer medium, a transfer roller and a detecting unit. A latent image formed on the latent image bearing unit by an exposure unit is developed by the developing unit with a liquid developer, and a developed image on the latent image bearing unit is transferred to a transfer. The transfer roller includes a cylindrical portion with a concaved portion formed in an axis direction of a circumferential surface of the cylindrical portion, and a transfer material supporting member fixed in the concaved portion and wound around a circumferential surface of the cylindrical portion to support a transfer material. The detecting unit is configured and arranged to detect a rotation position of the transfer roller when the transfer medium and the transfer roller come into contact with each other with the transfer material being interposed therebetween. | 01-13-2011 |
20110044745 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - An image forming apparatus includes a transfer belt onto which an image is transferred, a roller around which the transfer belt is wound, a transfer roller that sandwiches the transfer belt with the belt driving roller, a transfer medium transporting unit, a guide portion, and a fixing unit. The transfer roller is arranged to form a transfer nip with the roller, and transfers the image from the transfer belt to a transfer medium. The transfer medium transporting unit vertically upwardly sucks the transfer medium, and transports the transfer medium with the image facing vertically down. The guide portion vertically upwardly sucks the transfer medium transported by the transfer medium transporting unit. The fixing unit has a heating roller and a pressing roller to form a fixing nip, and fixes the image guided by the guide at the fixing nip. | 02-24-2011 |
20110200351 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - An image forming apparatus includes an image carrier belt for carrying an image, a transfer roller rotating on a rotating shaft and forming a transfer nip with the image carrier belt downward in a vertical direction from a virtual horizontal plane perpendicular to the vertical direction including the centerline of the rotating shaft, an airflow-generating unit for generating a first airflow directed between the image carrier belt and a transfer surface, and a second airflow directed towards the transfer surface from below in the vertical direction, where the image has been transferred by the transfer nip onto a transfer material, and where the image on the transfer material has been transferred onto the transfer surface. | 08-18-2011 |
20110318068 | IMAGE-FORMING DEVICE AND IMAGE-FORMING METHOD - An image-forming device comprising: an image-carrier belt that carries an image; a belt-driving roller that causes the image-carrier belt to move, the image-carrier belt being engaged around the belt-driving roller; a tension roller that applies a tension to the image-carrier belt, the image-carrier belt being engaged around the tension roller; a transfer roller having a concaved portion and a gripper, the transfer roller coming into contact with the tension roller interposed by the image-carrier belt, and transferring the image that is carried by the image-carrier belt onto the transfer material; a contacting/diverging part that causes the tension roller to move and that causes the transfer roller and the image-carrier belt to come into contact with or diverge from one another; a delivery part that delivers the transfer material that is gripped by the gripper; and a support member that pivotally supports the transfer roller and supports the delivery part. | 12-29-2011 |
20120063820 | IMAGE-FORMING APPARATUS AND IMAGE FORMING METHOD - An image-forming apparatus includes a transfer roller having a recessed portion in a circumferential surface; a driving portion for rotatably driving the transfer roller; an image carrier belt for carrying an image; a tension roller around which the image carrier belt is wound for making contact with the transfer roller interposed by the image carrier belt; a biasing portion for biasing the tension roller towards the transfer roller; and a position-regulating portion that, when the transfer roller rotates and the transfer roller and the image carrier belt make contact, causes a position to be maintained at which the image carrier belt wound around the tension roller intersects a virtual circumferential surface that is an extension of the circumferential surface of the transfer roller into the recessed portion. | 03-15-2012 |
20120121307 | CLEANING DEVICE, IMAGE FORMATION DEVICE, AND IMAGE FORMATION METHOD - A cleaning device includes a cleaning roller which contacts an intermediate transfer belt for carrying an image developed using a liquid developer, a cleaning roller which contacts the other cleaning roller and has a greater axial length than the other cleaning roller, and a rubber blade which contacts the cleaning roller and has a greater axial length than the cleaning roller. | 05-17-2012 |
20140284177 | RECORDING TRANSPORT DEVICE AND RECORDING DEVICE MEDIUM - An ink jet printer includes a cleaning blade that cleans the surface of a transport belt that attracts a sheet of recording paper by electrostatic adsorption and transports the attracted recording paper, and a pressing roller. The width of the cleaning blade is smaller than the width of the pressing roller that is located downstream of the cleaning blade, and thus, ink, paper dust, and the like that have escapes from both ends of the cleaning blade to the outside and have not been wiped off are caught by the pressing roller. | 09-25-2014 |
20140292907 | RECORDING APPARATUS - A recording apparatus includes a transport belt including an inner layer and an outer layer containing a hydrophobic material and having a supporting surface on which a recording medium is supported, a charging device for the transport belt, a line head having a nozzle, and at least either a capping unit or a wiping unit in a region opposing the supporting surface of the transport belt. While an ink is ejected onto the recording medium, the distance between the supporting surface and at least either the capping unit or the wiping unit is larger than the distance between the nozzle of the line head and the supporting surface. The charging device electrically charges the outer layer with an AC current with a frequency in the range of 10 Hz to 200 Hz. | 10-02-2014 |
