摘要： A fixing device includes a cylindrical heat roller, a heating element, a pressure roller, and an auxiliary roller. The heating element is provided inside the heat roller and configured to apply heat to the heat roller. The pressure roller is configured to be pressed against the heat roller to form, with the heat roller, a nip area where a recording paper sheet is to be nipped. The auxiliary roller is provided inside the heat roller and configured to be pressed toward the pressure roller with a peripheral wall of the heat roller in between. An outer peripheral surface of the auxiliary roller pressed against an inner peripheral surface of the heat roller is formed into an inverted crown shape so that an outside diameter of the auxiliary roller gradually decreases from both axial ends of the auxiliary roller toward an axial center thereof.

摘要： A belt feeding unit includes a rotatable belt, a first stretching roller for stretching the belt, and a second stretching roller including a stretching portion for stretching the belt. A first member is provided at one end portion of the stretching portion with respect to a widthwise direction of the belt and perpendicular to a movement direction of the belt. The first member is movable relative to the stretching portion to change a position of one end of the stretching portion at the one end portion. In addition, a second member is provided at the other end portion of the stretching portion and is movable relative to the stretching portion to change a position of the other end of the stretching portion at the other end portion. When the belt shifts in the widthwise direction to contact the first member, the first member moves relative to the stretching portion to incline the stretching portion relative to the first stretching roller, and the second member does not prevent movement of the stretching portion by the first member.

摘要： An image forming apparatus (100) is equipped with a plurality of photoreceptor drums (31A to 31D), an intermediate transfer belt (41), a separating and contacting mechanisms (20), a tension roller (44), a meandering correction mechanism, and a controller. The separating and contacting mechanism (20) displaces the intermediate transfer belt (41). The meandering correction mechanism increases and decreases a biasing force applied to each of the opposite end portions of the tension roller (44) according to the amount of movement of the intermediate transfer belt (41) in the axial direction (94) of the tension roller (44). The controller, during a non-image forming period, at a predetermined timing during rotation of the intermediate transfer belt (41), executes a belt displacement process in which the intermediate transfer belt (41) is displaced from a predetermined reference position and then returned to the reference position.

摘要： A belt-deviation suppression structure includes a contact member, receivers, and multiple link members. The contact member is in contact with a rotatable belt and extends longitudinally in an intersecting direction that intersects a moving direction of the belt. The receivers are provided at opposite sides of the contact member in the intersecting direction and receive a pressing force from the belt as the belt moves in the intersecting direction. The link members are arranged in the intersecting direction. Each link member has a first end that is connected to a base in a rotatable manner about an axis extending in the moving direction and has a second end that is connected to the contact member in a rotatable manner about an axis extending in the moving direction.
