ABSTRACT:
An image forming apparatus, includes: a rotatable photosensitive member; a charging brush for uniformly charging the photosensitive member; a light scanning and irradiating portion for illuminating the photosensitive member scan-wise; a developing roller for supplying the toner to the static latent image on the photosensitive member to create a toner image; and a rotatable transfer roller arranged opposing the photosensitive member and urged against the photosensitive member by urging elements arranged around both ends thereof for allowing the toner image to a print medium. In this arrangement, the peripheral surface speed of the transfer roller is set at a speed slower, by less than about 2.3%, relative to the peripheral surface speed of the photosensitive member, and the length of the transfer roller is set shorter by the distance not exceeding about 6 mm than the maximum width of the reproducible print media, in the direction of the length.
