Abstract
PURPOSE:To prevent a separation claw from deforming thermally and to preclude the generation of a roll flaw and the occurrence of a jam by separating a separation claw at the no-paper feed part of a fixing roller from the fixing roller in response to a paper feed size detection signal. CONSTITUTION:Separation claws 23a-23c are arranged on the fixing roller 21 and brought into contact with and separated from the roller 21 through solenoids 26a-26c. The temperature of the no-paper feed part possibly rises 50-60 deg.C above set temperature because heat radiation by a form is small. For the purpose, the separation claw 23c is separated in case of, for example, A5 size in response to the signal of a feed paper size detecting means. Consequently, the separation claw 23c is prevented from deforming thermally to prevent the fixing roller 21 from being flawed and a jam from occurring owing to deformation.
