Abstract

A photosensitive member unit is detachably mountable to a main assembly of an image forming apparatus. The photosensitive member unit includes a photosensitive member rotatable about a rotational axis thereof, a rotatable first helical gear portion; and a second helical gear portion integrally rotatable with the first helical gear portion. A twisting direction of a tooth of the second helical gear portion is the same as a twisting direction of a tooth of the first helical gear portion, and a helix angle of the tooth of the second helical gear portion is greater than a helix angle of the tooth of the first helical gear portion.
