heating an outer peripheral surface of the rotatable member, the heating
device including a heater for forming a heating nip portion in
cooperation with the rotatable member; back-up device for forming a
conveying nip portion in cooperation with the rotatable member, the
conveying nip portion conveying the recording material; and control
device for controlling a temperature of the heater and a rotation of the
rotatable member, wherein the apparatus has a cleaning mode to remove
toner from the heating device, and the control device rotates or
reversely rotates the rotatable member in a condition that the heater
dissipates heat in the cleaning mode. By the virtue of the present
invention, it prevents stain caused by the off-set of toner the recording
