Abstract
An image forming apparatus includes an image forming station for forming a toner image on a sheet; an image heating portion including a flexible heating roller and a pressing roller to form a nip, the image heating portion being effective to heat while feeding the sheet, by the nip; a pressing state switching portion for switching a state of the nip between a pressing state and a released state; and a sheet feeding position detector for detecting misalignment of the sheet relative to a feeding reference position with respect to a direction perpendicular to a feeding direction of the sheet; wherein when the sheet feeding position detector detects the misalignment, the pressing state switching portion permits the nip to feed at least one sheet in a state of the misalignment, and then switches the nip to the released state and then switches to the pressing state.
