摘要： An image forming apparatus provided with a photoreceptor with an internal gear includes the internal gear in a photoreceptor drum, a pinion gear in engagement with the internal gear, and a cleaning unit and a developer unit which apply contact pressure onto the photoreceptor drum. The pinion gear is provided in such an area that a resulting force of the contact pressure respectively applied from the process elements does not cause a distortion of the photoreceptor drum which exceeds an axial backlash determined in initialization according to a distance between axes of the pinion gear and the internal gear. The described arrangement prevents interference between non-driving surfaces of the internal gear and the pinion gear. As a result, a smooth rotary motion of the photoreceptor drum can be ensured, thereby preventing an image defect caused by an unstable rotary motion of the photoreceptor drum.

摘要： An object of the invention is to provide an image forming apparatus in which a unit can be attached to the apparatus body in a status where a correct positional correlation between a photoconductive drum and each of other process devices mounted on a unit is maintained. A photoconductive drum is positioned within a copier body by a rotating drive shaft, and the other process devices mounted on a process unit are positioned within a copier body by a boss and a locking member. The boss positions the rotating drive shaft within the copier body. Since the locking member is fitted onto a front-side end of the rotation drive shaft, the locking member is positioned within the copier body by the rotating drive shaft. The other process devices mounted on the process unit are positioned within the copier body by the rotating drive shaft via the boss and the locking member. Accordingly, the photoconductive drum and each of the other process devices, which should maintain a predetermined positional correlation with each other within the copier body, are both positioned within the copier body by the rotating drive shaft.

摘要： A charging device which has a grid disposed between a discharge element and the photosensitive drum. The grid is formed of a regulating portion having a mesh configuration for the range opposing the image area on the photosensitive drum and non-regulating portions with openings for the range opposing the non-image area. The flow of ions discharged from the discharge element is regulated as to their passage through the grid thereby so as to be uniform and charge the image area on the photosensitive drum uniformly. The flow of ions reaches the non-image area without being shaded by the grid, so as to enhance the surface potential for prevention against toner adherence.

摘要： A protecting cover and a pickup device, each having a hooking portion, are rotatably provided at the flank of an image forming apparatus. The rotational centers of the protecting cover and the pickup device and the hooking portions are arranged in such geometry that the hooking portions become engaged with each other only in the range from a predetermined trace intersection to the flank of the image forming apparatus when the protecting cover is rotated from its usage position toward its retracted position at the flank of the image forming apparatus. The pickup device is stopped at the starting position of engagement where the hooking portions are positioned at the trace intersection when sheet feed is not made, and is moved to the operating position when sheet feed is to be made. The protecting cover is constructed so as to rotate in linkage with the rotation of a paper feed tray which is rotatably provided at the flank of the image forming apparatus.

摘要： A developing unit includes a developing tank and a toner hopper. The developing tank is disposed to oppose a recording medium rotatably mounted to an image forming apparatus utilizing electrophotography. A developing member conveys a developer and attaches toner to an electrostatic latent image formed on the recording medium to develop the electrostatic latent image. The toner hopper has a toner supply port for supplying toner to the developing tank through a toner replenishing port formed in the developing tank. The developing tank is detachable in a direction of a rotating shaft of the recording medium, and is movable in a direction perpendicular to the direction of the rotating shaft of the recording medium so as to separate from or oppose the recording medium. The toner hopper has a shutter for opening/closing an opening of the toner supply port. A moving mechanism mounted on the developing tank simultaneously provides movement of the developing tank in the direction perpendicular to the direction of the rotating shaft of the recording medium and movement of the toner hopper shutter to open/close the toner supply port when manipulated.
