摘要： A photosensitive drum includes a cylindrical member having a photosensitive body disposed thereon, and first and second helical gears arranged axially side-by-side on one end of the cylindrical member. The first helical gear is disposed axially outward of the second helical gear, and the first helical gear has an outer diameter greater than an outer diameter of the second helical gear. The first helical gear meshes with a drive gear to rotatingly drive the drum. A sleeve gear of a developing sleeve is selectively engaged with one of the first and second helical gears, depending upon a kind of toner used.
