    摘要： The present invention relates to a process cartridge removably mountable on an image forming apparatus comprising a support, a rotary member having an image bearing surface and rotatably supported by the support, and a rotatable developing roller supported by the support, for carrying developer thereon and supplying the developer to the image bearing surface to develop a latent image formed on the image bearing surface. A first gear is arranged coaxial with the rotary member, a second gear is arranged coaxial with the developing roller and meshed with the first gear, and a guide means is provided for guiding the developing roller in a direction toward and away from the rotary member. The direction in which the developing roller is guided by the guide means is inclined with respect to a straight line connecting the center of rotation of the rotary member to the center of rotation of the developing roller, by an angle between 0.7.times..THETA. (.THETA. is a pressure angle of the second gear) and 1.3.times..THETA.. The cartridge further includes a bias means for biasing the developing roller toward the image bearing surface.

    摘要： A recording apparatus comprising a platen for supporting a sheet at a recording area, feeding means for feeding the sheet to the platen, recording means for recording an image on the sheet at the recording area, and an urging member disposed at a downstream side of the recording area and adapted to urge the sheet against the platen. The urging member has an urging surface for urging the sheet against the platen when the recording means is recording the image on the sheet.

    摘要： There is provided an image forming apparatus such as a copying apparatus having a sensor to detect the front edge of an original and a sensor to detect the front edge of a paper onto which a copy image of the original is formed, in which the copying operation is started in accordance with the result of the detections by both sensors. A distance which is obtained by adding a distance from an exposing position of a photosensitive drum and a distance from an original feed roller to an exposing position is equalized to a distance from the copy transfer position of the photosensitive drum to a paper feed roller. If such distances differ, the feeding timing of the original or paper is delayed in accordance with the difference between those distances. Thus, the cheap and small copying apparatus can be realized without using an expensive control system such as a registration roller.

    摘要： The present invention provides a printing apparatus and a printing method, in which a very thick and rigid printing medium such as board paper can be conveyed with stable conveyance accuracy, and in which a high-quality image can be printed thereon. In order to achieve this, paper on a front tray is conveyed onto a rear tray approximately along a plane containing a position on a platen, and then the paper is conveyed onto the front tray through the position on the platen. When the paper passes through the position on the platen, an image is printed on the paper.
