| 20090162087 | IMAGE FORMING APPARATUS, IMAGE FORMING STRUCTURAL BODY, METHOD OF MOUNTING IMAGE FORMING STRUCTURAL BODY AND METHOD OF PULLING OUT IMAGE FORMING STRUCTURAL BODY - The present invention provides an image forming apparatus comprising: a conveyer that conveys a developer image or a transfer medium to which the developer image is transferred; an image carrier that carries the developer image transferred to the conveyer or the transfer medium which the conveyer conveys; a latent image forming unit that forms the latent image on the image carrier; a developing unit that develops the latent image formed on the image carrier and forms the a developer image; a transfer unit that transfers the developer image formed on the image carrier; and a restricting unit that restricts the movement of the image carrier and the latent image forming unit in at least two directions and a rotational direction of the image carrier. | 06-25-2009 |
| 20090169262 | Developing device, image forming apparatus and developer cartridge - A developing device includes: a developer carrying member that supplies developer to an image carrying member; plural developer supply members,.containing different color developers, that supply the developers to the developer carrying member in a developer supply position; a conveyance member that sequentially conveys the plural developer supply members to the developer supply position; and a peeling member that peels off developer, remained after supply of the developer by the developer carrying member to the image carrying member, from the developer carrying member. | 07-02-2009 |
| 20090169269 | Developing unit, developing device and image forming apparatus - A developing unit includes: a developer carrying member that visualizes an electrostatic latent image held on an image carrying member using magnetic developer; a peeling member that peels off the magnetic developer held on the developer carrying member by a magnetic force; and a movement controller that controls movement of the peeling member, when the peeling member peels off the magnetic developer, the movement controller moving the peeling member to a position close to the developer carrying member, and when the peeling member has peeled off the magnetic developer, the movement controller moving the peeling member to a position away from the developer carrying member. | 07-02-2009 |
| 20090244571 | IMAGE FORMING APPARATUS - An image forming apparatus includes: an image output unit that outputs an image; and an image processing unit that converts an input image signal to an output image signal and outputs the image signal to the image output unit, the image output unit having: an image carrier that carries at least a latent image; plural developer containers containing mutually different color developers used for developing the latent image carried on the image carrier; and a transport member for repeated operations of attachment of the developer contained in one of the plural developer containers, transport of the attached developer to the image carrier, and removal of remaining developer, and the image processing unit having a change unit that changes a color conversion characteristic of an image signal in correspondence with color mixture of the mutually different color developers. | 10-01-2009 |
| 20090269115 | IMAGE FORMING APPARATUS - An image forming apparatus includes: an image carrier; a developing device that supplies one of plural color developers to the image carrier and forms a developer image; a transfer unit that transfers the developer image to a recording medium; a fixing unit that fixes the developer image; a transport path for transporting the recording medium from a supply position to an exit port; a return path for transporting the recording medium subjected to the fixing process to a position upstream of the transfer unit for performing subsequent processes on a developer image of another color developer; and a plane, including a junction of the transport path and the return path and a center of rotation of the developing device, being provided at a 90°—or wider angle with respect to a plane including a transfer position and the center of rotation of the developing device, on an upstream side of the another plane in a transport direction of the recording medium. | 10-29-2009 |
| 20090295077 | TRANSPORT DEVICE AND IMAGE FORMING APPARATUS - A transport device includes: a positioning member provided in a sheet transport path, used for positioning of a print sheet in a direction orthogonal to a sheet transport direction; and a skewed roller that transports the print sheet while skewing the print sheet toward a direction of the positioning member, a transport roller being provided in a position different from the skewed roller in the sheet transport direction. | 12-03-2009 |
| 20100124450 | IMAGE FORMING APPARATUS - An image forming apparatus includes: an image carrier that rotates; a developing unit that visualizes an electrostatic latent image carried on the image carrier with a color developer into a developer image; a transfer unit that transfers the developer image carried on the image carrier to a sheet in a predetermined transfer position; a fixing unit that fixes the developer image transferred by the transfer unit to the sheet; a transport unit that transports the sheet to which the color developer image has been fixed by the fixing unit, and returns the sheet to the transfer position for transferring a developer image of another color developer to be superposed on the developer image having been fixed to the sheet; and an adjustment unit that performs adjustment to reduce a time difference between time for returning the sheet by the transport unit and time for an integer number of rotations of the image carrier. | 05-20-2010 |
| 20110013961 | CONVEYANCE MECHANISM AND IMAGE FORMING APPARATUS - A conveyance mechanism includes a first conveyed material storage section and a second conveyed material storage section that respectively store a first conveyed material and a second conveyed material. When a position of the first conveyed material storage section is changed to a conveyed position where the first conveyed material is to be conveyed, a discharge destination of a discharge member is switched to a first conveyed material discharge section. When the position of the first conveyed material storage section is changed to an evacuation position evacuated from the conveyed position, the discharge destination of the discharge member is switched to a second conveyed material discharge section. | 01-20-2011 |
| 20110052264 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS - A developing device includes: plural developing units; a rotary body, where the plural developing units are attached, that rotates so as to place one of the plural developing units in a developing position to develop a subject of development; a first driving unit that drives the rotary body; a second driving unit that drives at least one of the plural developing units; and a regulatory mechanism that regulates a position of the rotary body using a rotational force caused in the rotary body in accordance with driving by the second driving unit. | 03-03-2011 |
