Abstract
In a fixing device, a stationary member is provided inside a belt member and pressed against a rotary pressing member via the belt member to form a nip between the rotary pressing member and the belt member through which a recording medium bearing a toner image passes. An expandable heating member is provided inside the belt member to face an inner circumferential surface of the belt member to heat the belt member. A regulator contacts a downstream portion of the heating member provided downstream from a center of the nip in a direction of rotation of the belt member to expand the downstream portion of the heating member.
