Abstract:
An image forming apparatus includes a fixing unit having a first shielding member configured to change an opening width of a first opening with respect to a longitudinal direction, a second shielding member configured to change an opening width of a second opening with respect to the longitudinal direction, and a controller that controls, on the basis of an output of a detector and size information of the recording material, the opening widths of the first opening and the second opening, so as to correspond to widths of non-passing portions of the recording material in the nip, by moving the first shielding member and the second shielding member in the longitudinal direction, respectively, when the recording material, having a size other than the maximum size, is inserted into the fixing unit.
