    Abstract: An image forming apparatus is designed to easily recover a jammed sheet nipped by a fixing roller and a pressure roller. In an entrance guide which guides a sheet to a fixing nip portion between the fixing roller and the pressure roller, 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 end of the sheet, 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 end in the discharging direction is locked.

    Abstract: An image reading apparatus reads an image of a sheet conveyed from an image forming apparatus. The image reading apparatus includes a transparent member including a first surface disposed on a first side on which the sheet is conveyed and a second surface disposed on a second side opposite to the first side, an image reading portion disposed on the second side and configured to read the image of the sheet at a reading position through the transparent member, an elastic member disposed to abut against the second surface of the transparent member and configured to press the transparent member toward the first side, and a guide disposed upstream of the reading position and configured to guide the sheet to the reading position. A downstream end of the guide contacts with the first surface of the transparent member and presses the transparent member toward the second side.
