摘要：
In a fixing device, a pressing member rotates in a predetermined direction of rotation. A flexible fixing member is disposed opposite the pressing member to rotate in accordance with rotation of the pressing member. A nip formation member is provided inside a loop formed by the fixing member and pressed against the pressing member via the fixing member to form a nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. A contact member pressingly contacts an outer circumferential surface of the rotating fixing member at both ends of the fixing member in an axial direction thereof.
