Provided is a fixing device including: a fixing belt; a pressure roller which pressurizes toner on a sheet that passes through a pressure area; a pair of retention members each including a shaft-supporting portion which rotatably guides one of both end portions of the fixing belt in an axial direction, and a restriction surface which restricts a movement of the fixing belt in the axial direction; and a frame including a pair of side plates which rotatably support both end portions of the pressure roller in the axial direction as well as support the fixing belt via the pair of retention members, in which attachment positions of the pair of retention members in the pair of side plates are provided such that a gap becomes larger on a downstream side of a passing direction of the sheet with respect to the pressure area than on an upstream side.

A fixing device includes a pressure member, and a holder. The pressure member forms a pressure area between the pressure member and a fixing belt.

The holder includes a plurality of slits and a blocking portion. The plurality of slits are arranged in an axial direction on the sliding surface upstream of the pressure area in a passing direction of a medium and guide movement of the lubricant from upstream to downstream in a rotational direction of the fixing belt. The blocking portion restricts an outflow of the lubricant from each of the slits and restricts a fall of the fixing belt into each of the slits.

A fixing device includes a fixing member, a pressure member, and a pair of retention members each including a restriction surface. The restriction surface restricts a movement of the fixing member in an axial direction. The restriction surface includes a first contact area and a second contact area. The first area is an area more on a downstream side of a passing direction of a medium than a center of a pressure area in the passing direction, and also closer to the pressure area than an apex of the fixing member on an opposite side of the pressure area. The first contact area and the second contact area are each tilted at a certain gradient so as to be set apart from the end portion of the fixing member in the axial direction from a side of the apex toward a side of the pressure area.

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

A fixing device heats and fixes a toner image formed on a sheet to the sheet. The fixing device includes a heat roller and a ground contact. The heat roller heats the toner image formed on the sheet. The ground contact grounds the heat roller. The ground contact includes a first electrical conductive member, a second electrical conductive member, and an electrical insulating member. The first electrical conductive member is electrically connected to the heat roller. The second electrical conductive member is positioned opposite the first electrical conductive member and grounds the heat roller. The electrical insulating member is interposed between the first electrical conductive member and the second electrical conductive member and insulates the first electrical conductive member and the second electrical conductive member from each other.

The fixing device includes a heating roller and a pressure roller. The heating roller has a rotating member, a heating member, and a support member. The heating member has a heater, a first terminal, and a second terminal. The heater generates heat by energization. The first terminal is connected to one end of the heater. The second terminal is connected to the other end of the heater. The first terminal protrudes from one end of the rotating member in the longitudinal direction of the rotating member and is hooked on a hook provided on the support member so as to be movable along the longitudinal direction. The second terminal protrudes from the other end of the rotating member in the longitudinal direction and is fixed to the support member so as not to be movable along the longitudinal direction.
