Abstract
PURPOSE:To transmit rotation from a driving shaft without generating rotary nonuniformity in a photosensitive drum, by providing an inner gear at the flange part of the photosensitive drum, and an outer gear at the driving shaft. CONSTITUTION:The inner gear 21 having a tapered serration 22 on its inner periphery is provided at the flange part 19 of the photosensitive drum 13, and the outer gear 30 having a tapered serration 29 on its outer periphery is provided at the driving shaft 28. And the rotation of the driving shaft 28 is transmitted to the photosensitive drum 13 by engaging the tapered serrations 22 and 29 of the inner and the outer gears 21 and 30. In such a way, since the rotation from the driving shaft 28 can be transmitted without generating the rotary nonuniformity in the photosensitive drum 13, it is possible to obtain an image with a few amount of density nonuniformity or blurring.
