Image forming apparatus

An image forming apparatus comprising:

• a fixing unit that has a heating roller configured to heat an unfixed image formed on a sheet, and a pressure roller configured to sandwich and press the sheet with the heating roller, the fixing unit fixing the unfixed image to the sheet;
• an operation lever that moves the pressure roller, the operation lever being movable to (1) a first position for positioning the pressure roller at a first pressing position where the pressure roller presses the heating roller with a first pressing force and (2) a second position for positioning the pressure roller at a second pressing position where the pressure roller presses the heating roller with a second pressing force smaller than the first pressing force;
• a housing that accommodates the fixing unit;
• an exterior cover that is provided in the housing so as to be openable and closable and forms an exterior of the image forming apparatus, the exterior cover being openable and closable in a close position and an open position in which the exterior cover is opened for discharging a sheet that has passed through the fixing unit onto an inner side of the exterior cover;
• and
• an abutting portion that is provided on the inner side of the exterior cover and abuts on the operation lever, wherein
• the abutting portion (1) abuts on the operation lever during movement of the exterior cover from the open position to the close position so as not to allow the exterior cover to be closed when the operation lever is located at the second position, and (2) does not abut on the operation lever during the movement of the exterior cover from the open position to the close position so as to allow the exterior cover to be closed when the operation lever is located at the first position.
