(54) | Fixing device and image forming apparatus |
(57) A fixing device (13) includes: a fixing belt (21); a heat portion (25); a pressure roller (23); a push member (22) that pushes the fixing belt (21) against the pressure roller (23); and a push pad (40) that is disposed on a surface of the push member (22) that opposes the fixing belt (21). A slide surface (40a) of the push pad (40) has a flat portion (41) substantially parallel to a convey direction of the recording medium and an arc-shaped portion (43) that bends toward the pressure roller (23) in a more downstream side than the flat portion (41) in the recording medium convey direction, the arc-shaped portion (43) includes a radius R2 of curvature larger than a radius R1 of curvature of the pressure roller (23) and a center 02 of curvature that is situated in a more upstream side than a straight line which passes a center O1 of curvature of the pressure roller (23) and is perpendicular to the recording medium convey direction.
