发明名称 IMAGE FORMING APPARATUS
摘要 Provided is an image forming apparatus capable of easily recovering a jam sheet nipped by a fixing roller and a pressure roller.;In an entrance guide which guides a sheet to a fixing nip portion between a fixing roller and a pressure rolle, a bending portion is provided on a back side of a guide face which guides the sheet to the fixing nip portion. Then, when the sheet to be discharged toward the entrance guide by a manual discharge member enters the back side of the entrance guide, a downstream side end in a discharging direction of the sheet is locked to the bending portion, and thus the central portion of the sheet in the sheet discharging direction is bent along the surface of the guide face by discharging the sheet in a state where the downstream side end in the discharging direction is locked.
