Abstract: An image forming apparatus includes an intermediate transfer belt and a developer unit. The image forming apparatus includes a cooling unit, a cleaning roller, and an auxiliary brush. The cooling unit cools a predetermined component by sending air by a fan inside the image forming apparatus. The cleaning roller removes remaining toner on the intermediate transfer belt at an upstream side of a region facing the developer unit in a rotationally moving direction of the intermediate transfer belt and at an upstream side of a region with which the image carrier is in contact in the intermediate transfer belt. The auxiliary brush located on an outer surface of the developer unit so as to close the clearance between the intermediate transfer belt and the developer unit and is in contact with the intermediate transfer belt to clean the intermediate transfer belt.

Abstract: A registration system suited to use in an imaging system, such as an inkjet printer, includes a first measuring device, such as an encoder, which provides information for monitoring a speed of a moving image receiving surface of the imaging system, such as a paper web. A second measuring device, such as a second encoder or a tension measuring device, provides information for monitoring a tension in the image receiving surface. A control system determines an actuation time for one of two marking stations, based on the information from the first and second measuring devices. This enables a registration of images applied to the image receiving surface by the two marking stations to take into account both changes in speed of the web and changes in tension in the web.

Abstract: A full color image developing device for a color printer is disclosed, in which a black developing unit employs a magnetic one-component developing system, and color developing units (except for black) employ a non-magnetic one-component toner. The diameters of the non-magnetic developing rollers are set smaller than those of the magnetic developing roller. This configuration makes it possible to extend the lifespan of the color printer as well as reduce the size and cost thereof.

Abstract: A color image forming apparatus capable of preventing an image skew by maintaining parallelism of scanning directions between respective photosensitive mediums and between the photosensitive medium and a transfer belt within a certain range. The color image forming apparatus includes an ITU/OPC cartridge, as a single unit, wherein a plurality of photosensitive mediums (OPC) and an intermediate transfer unit (ITU) are integrally mounted. In the ITU/OPC cartridge, an OPC frame and the ITU frame respectively supporting the OPC and the ITU are separably connected, so that the OPC and the ITU having different lifespan can be independently replaced.

Abstract: In a belt apparatus used for image formation structured such that processing unit used for image formation are placed around a belt extended between at least two rollers and at least one of the processing unit acts on a roller so as to impart a rotational load thereto, it is possible to avoid a reduction in the image quality of a transfer image on the belt caused by the roller that supports the belt receiving variations in the load due to the movement towards or away from the belt of a cleaning blade. A drive source is connected to the roller to which directly receiving the load variation making this roller the drive roller for the belt.
