Abstract
Upon occurrence of jamming in an apparatus, an electrification unit 4 ceases electrification of a surface of a photosensitive drum 3 and, simultaneously, an exposure unit 5 starts to expose the entire surface in a width direction to light. Further, a development unit 6 forms a toner adhesion region T on the photosensitive drum 3 and, also, stops a drum motor and a belt motor in such a manner that the toner adhesion region T stops at a transfer nip section N. Thus, it is possible to alleviate a rub between the photosensitive drum 3 and a conveyance belt 8 at the time when jamming is cleared, and to suppress generation of scratches on the photosensitive drum 3 and a surface of the conveyance belt 8.
