Abstract

Flanges used in a photosensitive drum to be regenerated are assembled in a regenerated electrophotography photosensitive drum employing a regenerated cylinder having a diameter enlarged by regeneration processes. The regenerated electrophotography photosensitive drum is obtained by enlarging the diameter of the photosensitive drum to be regenerated whose photosensitive film has not functioned normally because of being used up or damaged during preparation or the like, cutting off the surface, including the photosensitive film, of the cylinder with predetermined precision with respect to the outer diameter and the surface, and forming a photosensitive film on the resultant regenerated cylinder. A flange with a bearing used in the photosensitive drum to be regenerated is assembled in the flange attachment position of the regenerated electrophotography photosensitive drum with a spacer placed for adjusting the inner diameter increment and axial contruction due to the diameter enlargement, thereby obtaining the regenerated electrophotography photosensitive drum unit.
