摘要： In a fixing device, a nip formation member is provided inside a loop formed by a fixing member rotating in a predetermined direction of rotation. A pressing member is pressed against the nip formation 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. The fixing member and the pressing member rotate and convey the recording medium bearing the toner image through the nip. The heat conduction member faces an inner circumferential surface of the fixing member to guide the fixing member sliding over the heat conduction member and to transmit heat to the fixing member. The heat conduction member includes a plurality of convex portions provided on an outer circumferential surface of the heat conduction member and contacting the inner circumferential surface of the fixing member.
