A method is disclosed for attaching a sheet for receiving toner removed from an image bearing member to a frame. The method includes the steps of adhering the sheet to the frame, using an adhesive, while bending the frame and releasing the frame after the sheet is adhered to the frame. A toner-guiding sheet for guiding toner removed from an image bearing member to a toner-receiving unit is also disclosed. The sheet is widened near a central portion in a longitudinal direction so that the sheet edge will conform to the bent shape of an attachment surface. A cleaning device is also disclosed. The cleaning device may include a frame and a sheet attached to the frame by an adhesive in a condition that a tension force is applied to the sheet. Further, the cleaning device may include a cleaning container having a wall that is thinner at a position near an attachment surface for a sheet than at a position away from the attachment surface, to facilitate bending of the attachment surface during application of a sheet to the attachment surface.

Provided are a process cartridge and an image forming apparatus having the process cartridge. The process cartridge is constituted as one of at least two types of cartridges, a first cartridge and a second cartridge, and used selectively by being made detachably attachable to a main body of an identical image forming apparatus. The first cartridge includes: a cleaning unit which removes toner remaining on a surface of a medium; a cleaning frame which receives toner recovered by the cleaning unit and has an opening; and a waste toner carrying unit which is provided in the opening and carries the toner in the cleaning frame. The second cartridge includes: a cleaning unit which removes toner remaining on a surface of a medium; a cleaning frame which receives toner recovered by the cleaning unit and has an opening; and a sealing member which seals the opening without the waste toner carrying unit being provided in the opening.

An electrophotographic image formation system forms an image on a recording material The system includes a process cartridge and an electrophotographic image forming apparatus to which the process cartridge is detachably mountable. The apparatus includes a main assembly and a main assembly antenna covered with a main assembly antenna outer casing member. The process cartridge includes an electrophotographic photosensitive member, a process device actable on the electrophotographic photosensitive member, a storing element storing information, a memory antenna for communication with the main assembly antenna, and a memory antenna outer casing member for covering the storing element and the memory antenna. Positioning is effected for a gap between the memory antenna and the main assembly antenna by contact between an outer surface of the memory antenna outer casing member and an outer surface of the main assembly antenna outer casing member of the main assembly antenna.
