Abstract
An image forming apparatus includes a rotatable image bearing member, a rotatable transfer member, a first driving source to drive the image bearing member, a second driving source to drive the transfer member, and a control portion. Based on a toner amount per unit area of the toner image transferred to each of a plurality of first divided regions on a plane of a recording material in a feeding direction, the control portion controls a driving speed of the transfer member while each of the plurality of the first divided regions passes through a transfer portion. The control portion acquires an index value correlating with a toner amount of the toner image transferred to each of a plurality of second divided regions of each first divided region in a widthwise direction, and controls the driving speed based on the index value while the first divided region passes through the transfer portion.
