A cylindrical structure is formed by a cylinder and a terminal engaging member, such as a gear or flange for rotating the cylinder. The terminal engaging member has a head which is inserted into the cylinder and a plurality of recesses by which the member is fastened to at least one end of the cylinder through bending and cutting the assocrated cylinder at plural parts thereof into the recesses of the terminal engaging member. In this mannaer, the joint between the cylinder and the terminal engaging member can be formed securely in a simple manner. The cylindrical structure may be employed, for example, as a photosensitive drum or a developing sleeve for electrophotography.

A process cartridge detachably mountable within an image forming system, includes an image bearing member, a processing device for acting on the image bearing member, a housing for supporting the image bearing member and the processing device, and a cover shiftable between a closed position where the image bearing member is protected and an open position where the cover is retracted from the protecting position. The cover is spaced apart from the housing at least in the retracted position and is provided with a protruded portion at its inner surface. An image forming system includes a mounting device for mounting a process cartridge, an air flow generating device for generating an air flow passing between the protruded portion and the cover, a transfer device for transferring a developed image formed on the image bearing member onto a recording medium, and a conveying device for conveying a recording medium.

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.

A blade member, mountable onto an electrophotographic image forming apparatus, such as copier, printer, facsimile, word processor, and the like, for removing residual matter from an electrophotographic photosensitive member, includes an elastic blade one side surface of which is flat in a longitudinal direction thereof and the other side surface of which has a vertical portion perpendicular to an end surface of the elastic blade, and an inclined portion inclined with respect to the vertical portion, the inclined portion having a larger thickness than the vertical portion, and a support member for supporting the elastic blade. A thickness (f) of a portion of the elastic blade, which is engaged by the support member at a side of the one side surface, is greater than a thickness (g) of a portion of the elastic blade which is engaged by the support member at a side of the other side surface.
