Abstract
An image-forming machine includes a photosensitive drum on which a toner image is to be formed on the peripheral surface thereof, a transfer drum onto which is removably fitted an image-forming sheet member onto which said toner image will be transferred, and a cleaning device that removes the toner remaining on the peripheral surface of the photosensitive drum after the transfer of image has been finished. The image-forming area on the peripheral surface of the photosensitive drum is defined inside the portions that correspond to both side edges of the transfer sheet member of the transfer drum. A cleaning blade in the cleaning device is present continuously over the image-forming area but does not extend up to portions that correspond to both side edges of the transfer sheet. The photosensitive drum includes a pair of flange members and a photosensitive drum body mounted to the flange members. A drive coupling member made of a resilient metal is secured to one of the flange members, and has a coupling protrusion that bites into the inner surface of the photosensitive drum body.
