Abstract:
A process unit for an electrophotographic image recording device having a main body and where toner image is electrophotographically formed on a photosensitive drum and the toner image is transferred onto paper, comprising:a photosensitive unit removably attached to the main body; a development unit removably attached to the main body; a first removal/attachment mechanism provided in the photosensitive unit; a second removal/attachment mechanism provided on the development unit; the first and second mechanisms being attachedable to/separable from each other, wherein when the first and second removal/attachment mechanisms are attached to each other, the photosensitive unit and the development unit form an integral unit that is removable from the main body; a pair of support bodies as the second removal/attachment mechanism projecting from the development unit to the photosensitive drum; a pair of drum shaft end portions as the first removal/attachment mechanism projecting from a drum shaft of the photosensitive drum on both sides of the photosensitive unit; a pair of pin members as the first removal/attachment mechanism provided such that they project from both sides of the photosensitive unit; and an engagement groove formed in each support body for receiving each corresponding drum shaft end portion and pin member and for aligning the photosensitive unit against the development unit when they are assembled.
