Abstract
An image forming apparatus includes a heating rotary member, a pressure rotary member, a nip portion formed by the rotary members, a temperature adjustment control section controlling a temperature of the heating rotary member to a target temperature, a cleaning web removing toner adhering to the heating rotary member, and a controller selectively executing one of a cleaning mode and a non-cleaning mode. A first basis weight and a second basis weight greater than the first predetermined basis weight are set, in a job that mixedly uses recording media with the first and second basis weights. When the controller executes the non-cleaning mode, the temperature adjustment control section sets a target temperature of a recording medium with a basis weight less than or equal to the first basis weight to a temperature lower than a target temperature of the recording medium in the cleaning mode.
