摘要： An image forming apparatus includes a movable image bearing member; a transfer device cooperative with the image bearing member to form a nip, through which a transfer material is passed to electrostatically transfer an image from the image bearing member onto the transfer material; where the resistance R range providing proper image transfer is determined in accordance with the equation:-9.16.times.10.sup.3 .times.v+11.68-0.65.ltoreq.log.sub.10 (R.times.L).ltoreq.-9.16.times.10.sup.3 .times.v+11.68+0.65where V (mm/sec) is movement speed of the image bearing member (v.gtoreq.40), R (ohm) is a resistance of the transfer device when a voltage of 3 KV is applied between the image bearing member and the transfer device, and L (mm) is a length of the nip measured in a direction of a generating line of the image bearing member.
