Abstract

The present invention relates to a cartridge detachably mountable to a main assembly of an image forming apparatus. The cartridge comprises a photosensitive member rotatable about a rotational axis thereof; a frame rotatably supporting the rotatable member; a rotatable first helical gear portion; and a second helical gear portion integrally rotatable with the first helical gear portion, the second helical gear portion being provided between the photosensitive member and the first helical gear portion, with respect to the rotational axis of the photosensitive member. A twisting direction of the tooth of the second helical gear portion is the same as a twisting direction of the tooth of the first helical gear portion, and a helix angle of the tooth of the second helical gear portion is larger than a helix angle of the tooth of the first helical gear portion.
