Abstract: The developing device includes a development container, a developer carrier, and a restricting blade. The development container has an opening. The developer carrier has a development area. The development container includes a pair of side frames, and a pair of side wall portions. In each of the pair of side wall portions, a seal member insertion hole extending through in the rotation-axial direction is formed at a position facing an end edge of the restricting blade in the rotation-axial direction. The developing device includes a blade-side side seal inserted in the seal member insertion hole to block a gap between the restricting blade and the side wall portion.

Abstract: A fixing device includes a heating section. The heating section includes a heater, a heater holding member, a heat-sensitive body, a cover member, and an urging member. The heater holding member holds the heater. The heat-sensitive body faces the heater. The cover member covers the heat-sensitive body. The urging member urges the cover member in a first direction which is toward the heater from the heat-sensitive body. The urging member extends in a second direction intersecting with the first direction and engages with the heater holding member and the cover member.

Abstract: A fixing device includes a fixing belt and a heating section. The heating section includes a heater and a heater holding member. The heater holding member has a main body portion and a plurality of ridges. The ridges include a plurality of first ridges and a plurality of second ridges. The first ridges are disposed on a central portion of the main body portion in a width direction of the fixing belt. The second ridges are disposed in an area of the main body portion at least partially extending, in the width direction of the fixing belt, from the central portion to each of opposite ends of the main body portion. The first ridges are disposed separated at a first interval. The second ridges are disposed separated at a second interval. The first interval is smaller than the second interval.

Abstract: A fixing device includes a fixing belt, a pressure member, and a heating section. The heating section faces an inner circumferential surface of the fixing belt. The heating section includes a heater and a heater holding member. The heater heats the fixing belt. The heater holding member holds the heater. The heater holding member has a first side surface, a second side surface, and an inclined slit. The first and second side surfaces are in contact with the inner circumferential surface. The first side surface has the inclined slit. The inclined slit is located in the first side surface in a direction of a rotational axis of the fixing belt. The inclined slit has one end on a side of the pressure member and the other end on an opposite side to the side of the pressure member. The other end is located nearer a middle (center) of the first side surface in the direction of the rotational axis than the one end.

Abstract: High-temperature heat generated from a fixing device is efficiently discharged to an outside an apparatus. A printer includes: a photosensitive drum; a transfer roller; a fixing device; and a duct frame that is mounted between two side plates disposed to oppose each other and disposed right over the fixing device with a lower surface opened. An upper inner surface of the duct frame is inclined in a short-edge direction of the duct frame, and an inclined upper end portion of the upper inner surface is provided with an aperture portion that discharges heat generated from the fixing device to an outside of the duct frame.

Abstract: An image forming apparatus includes a fixing device, a shutter, a lock member and an attachment member. The fixing device is supported by an apparatus main body. The shutter is movable to a close position and to an open position. The lock member is movable to a holding position holding the shutter to the close position and an allowable position allowing the shutter to move from the close position to the open position. The lock member is moved to the holding position to hold the shutter to the close position in a state where the attachment member is detached from the apparatus main body. In the middle of attaching the attachment member to the apparatus main body, the attachment member moves the lock member from the holding position to the allowable position and then moves the shutter from the close position to the open position.

Abstract: A heater holding member circulatably guides a fixing belt and holds a heater that heats the fixing belt. A stay sheet metal reinforces the heater holding member. The heater holding member has a base plate and side walls. The stay sheet metal is placed on the base plate. A side wall is erected on either side of the base plate in a short direction thereof. A pocket which keeps the stay sheet metal is formed in each side wall. The stay sheet metal has a top plate and side plates. A side plate bends and extends from either edge of the top plate in a short direction thereof. A slit is formed in each side plate such that the side plates are kept in the pockets of the heater holding member.
