Abstract: An image forming apparatus feeds a paper picked up by a pickup roller directly to a photoconductive drum and controls a linear velocity of the pickup roller so that it is slower than that of the photoconductive drum. The different linear velocities of the pickup roller and the photoconductive drum produces different velocities at the transfer nip (the area of contact between the photoconductive drum and a transferring roller) and the point where paper is picked up by the pickup roller. To compensate for the different velocities, the pickup roller can be rotated faster than the photoconductive drum for an angle that corresponds to the velocity difference. Additionally, when a velocity difference occurs between two rollers for feeding the paper, one of the rollers can be further rotated to compensate for the velocity difference.
