摘要:
A transfer roller is spaced away from the outer surface of a photosensitive drum by a specified distance to prevent the abrasion and damage of the photosensitive drum by the contact of the transfer roller and the photosensitive drum. The transfer roller not in contact with the photosensitive drum can be formed to have a sufficient hardness without damaging the outer surface of the photosensitive drum. Further, since the transfer roller has a sufficient hardness, cleaning blades can be held in without damaging the transfer roller with a sufficiently large force without damaging the transfer roller, thereby securely scraping off toner and the line adhered to the transfer roller and preventing the rear surface of a transfer sheet from being smeared.
