A process cartridge detachably mountable to an image forming apparatus includes a frame member, a photosensitive member, a rotary member mounted on the frame member, where the rotary member constitutes a process device. A blade member is mounted on the frame member in proximity with the rotary member. A sealing member has a rotary seal portion for sealing a space formed between the frame member and the rotary member. A blade seal portion seals a space formed between the frame member and the blade member. A compressible seal portion, provided in a portion of the rotary seal portion and the blade seal portion, seals a space formed adjacent to a longitudinal end portion of the blade member.

A photosensitive drum includes a cylindrical member having a photosensitive body disposed thereon, and first and second helical gears arranged axially side-by-side on one end of the cylindrical member. The first helical gear is disposed axially outward of the second helical gear, and the first helical gear has an outer diameter greater than an outer diameter of the second helical gear. The first helical gear meshes with a drive gear to rotatingly drive the drum. A sleeve gear of a developing sleeve is selectively engaged with one of the first and second helical gears, depending upon a kind of toner used.

The present invention is characterized by an image bearing member, a toner carrying member for directing toner to the image bearing member and a magnet disposed within the toner carrying member, and in that the image bearing member and the magnet are positioned by a common positioning member. With above construction, it is possible to provide a process cartridge and an image forming system, which can remarkably the accuracy of attachment positions of an image bearing member and a magnet, thus remarkably enhancing the image quality.
摘要:
An image forming system includes a process cartridge having an image bearing member, processing structure acting on the image bearing member, a toner container containing toner used in a developing operation, and a gripper used when the process cartridge is mounted within the image forming system. The gripper also serves as an aiding member for removing a seal sealingly closing an opening of the toner container. With the foregoing construction, it is possible to provide a process cartridge and an image forming system capable of removably mounting a process cartridge therein, which can prevent an operator from forgetting to remove a seal prior to using a new process cartridge.
