摘要：
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.
