Abstract
An image forming apparatus includes an endless rotatable belt, a rotary pressing member, a pressing member, a driving unit, a heating roller, a temperature detection member, and a control unit. The rotary pressing member is configured to form a nip portion between the rotary pressing member and the belt, the nip portion being a portion in which a toner image borne by a recording material is fixed to the recording material while the recording material is nipped and conveyed. The control unit is configured to control the driving unit such that the driving unit does not start to rotate the belt during a period of time for a preparatory operation if a temperature of the heating roller is higher than a predetermined temperature, wherein the preparatory operation is an operation performed for enabling image formation after an error or a jam is handled.
