Abstract:
1. A fixing device for fixing a toner image carried on a recording medium, the fixing device comprising: a rotatable fixing roll member; a fixing belt member wound on the fixing roll member so as to be rotatable; and a walk adjustment mechanism that changes a walk width of the fixing belt member in accordance with a width of the recording medium, wherein the walk adjustment mechanism changes the walk width of the fixing belt member between one walk width for a recording medium having a maximum width and another walk width for recording media other than the recording medium having the maximum width, and wherein the walk adjustment mechanism adjusts the walk width of the fixing belt member so that the walk width for the recording medium having the maximum width is less than a margin width of the recording medium having the maximum width in an orthogonal direction with respect to a traveling direction of the recording medium.
