20110076052 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - An image forming apparatus includes: a latent image bearing member on which a latent image is formed; a developing unit that develops the latent image using a liquid developer; a transfer member onto which the image is transferred; a cleaning unit that cleans the latent image bearing member; a cleaning roller, to which a bias is applied, that cleans the transfer member by making contact with the transfer member; a blade that cleans the cleaning roller by making contact with the cleaning roller; a cleaning blade that cleans the transfer member cleaned by the cleaning roller by making contact with the transfer member; a holding unit that holds collected material scratched by the blade and the cleaning blade; an application unit that applies the collected material to the cleaning roller; and a transport channel that transports the collected material collected by the cleaning unit to the holding unit. | 03-31-2011 |
20110262170 | CLEANING APPARATUS AND IMAGE FORMING APPARATUS - A cleaning apparatus includes a first cleaning roller, and a second cleaning roller. The first cleaning roller is contrived to contact to a circumferential surface against a moving member to be cleaned and to apply a bias to the member to be cleaned while rotating such that the circumferential surface of the first cleaning roller moves in a same direction as the member to be cleaned moves. The second cleaning roller is contrived to contact to the member to be cleaned after the member has been cleaned by the first cleaning roller and to rotate such that a circumferential surface of the second cleaning roller moves in a direction opposite a direction in which the member being cleaned moves. | 10-27-2011 |
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 |
20120263500 | TRANSFER DEVICE AND IMAGE FORMATION APPARATUS - In order to provide a device that can suppress speed fluctuations of an image carrier and prevent image disturbance caused thereby, tension rollers elastically supported by springs are disposed either side of a secondary transfer position where an intermediate transfer belt and a secondary transfer roller oppose one another, the secondary transfer roller having a recess part for accommodating a gripping part for gripping a recording material. The intermediate transfer belt is rotatably driven by a belt drive motor around which the intermediate transfer belt is wound in a position that is different from the secondary transfer backup roller. The speed fluctuations of the intermediate transfer belt that are generated in the secondary transfer position due to the rotation of the secondary transfer roller are absorbed by the two tension rollers and have no effect on image formation. | 10-18-2012 |
20130286093 | HEAD DRIVING MECHANISM AND PRINTING APPARATUS - A head driving mechanism includes a first cam follower an end portion of which is attached to a first holding unit and the other end portion of which includes a first sliding-contact surface disposed in sliding contact with a cam, and a second cam follower an end portion of which is attached to the second holding unit and the other end portion of which includes a second sliding-contact surface disposed in sliding contact with the cam. The first cam follower and the second cam follower are each displaced by rotation of the cam so as to move the first printing head and the second printing head, while the first sliding-contact surface and the second sliding-contact surface are in sliding contact with an outer circumferential surface of the cam. | 10-31-2013 |
