Abstract
An image forming apparatus includes a transfer member which transfers a toner image formed on an image bearing member to a transfer material; a transfer bias application unit which applies bias to the transfer member; a controller which executes a mode for making a first bias applied to a first predetermined area arranged at a leading edge of a transfer material with respect to a conveying direction of the transfer material to be less than a second bias applied to a second predetermined area arranged in a central area of the transfer material; and an obtaining portion which obtains image information of an image formed in each area obtained by dividing an area corresponding to the leading edge area into plural pieces in the width direction, wherein the controller controls the first bias based on image information obtained by the obtaining portion at the time of the mode.
