Abstract
An image forming apparatus includes a transfer member to transfer a toner image borne on s photosensitive member onto a conveyed recording material on receiving voltage from a power supply. Where an image is formed at a transfer portion on a first recording material and a subsequent second recording material, a time interval is changed to a first or second interval based on information concerning the transfer onto the first recording material. The second recording material has a second width greater than a first width of the first recording material. The time interval is from when a first recording material trailing edge passes through the transfer portion to when a second recording material leading edge reaches the transfer portion. The photosensitive member rotates one or less rotations during the first interval and rotates one or more rotations during the second interval.
