Abstract: A fixing device (50) includes a fixing belt (70), a pressure member (80), and a heating section (90). The heating section (90) faces an inner peripheral surface of the fixing belt (70). The heating section (90) includes a heater (HT), a first heat sensitive body (SM11), and a second heat sensitive body (SM21). The second heat sensitive body (SM21) differs from the first heat sensitive body (SM11). The heater (HT) has a first heater portion (AE1). The first heater portion (AE1) is one end portion of a pair of end portions of the heater (HT) in a longitudinal direction thereof. The first heat sensitive body (SM11) and the second heat sensitive body (SM21) face the first heater portion (AE1) and are aligned in a conveyance direction (DC) of a sheet (S).

Abstract: A fixing device includes a fixing belt, a pressure member, a first holding member, and a second holding member. The fixing belt is endless and includes a first rim and a second rim. The pressure member presses the fixing belt by being in contact with an outer circumferential surface of the fixing belt and rotates about a rotation axis of the pressure member. The first holding member is attached to the fixing belt and holds the first rim of the fixing belt. The second holding member is attached to the fixing belt and holds the second rim of the fixing belt. The second holding member includes a base portion, a main portion, and a protrusion. The main portion protrudes from the base portion. The protrusion protrudes from the main portion in a direction away from the base portion.

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.

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.
