Abstract
An image forming apparatus includes a transfer portion to transfer a toner image to a recording material, a fixing portion having a heating unit and a cylindrical rotary member and to fix the toner image to the recording material, a fixing drive portion to drive the cylindrical rotary member, and a controller. In a case in which images are formed on a plurality of recording materials, the controller controls the fixing drive portion based on a time period from a time when a trailing edge of a preceding recording material passes through the fixing portion to a time when a leading edge of a subsequent recording material passes through the fixing portion so that a second rotation speed of the cylindrical rotary member when conveying the subsequent recording material becomes lower than a first rotation speed of the cylindrical rotary member when conveying the preceding recording material.
