摘要： A fixing device includes a heat source, a fixing roller, a pressure roller, an elastic layer, a pressing portion, a restricting portion and a driving unit. The fixing roller is heated by the heat source. The pressure roller is held in contact with the fixing roller and forms a fixing nip portion through which a sheet is to be passed. The elastic layer is formed on an inner layer of the fixing roller. The pressing portion presses one roller of the fixing roller and the pressure roller against the other roller while compressing the elastic layer. The restricting portion restricts a compression amount of the elastic layer lest the compression amount should exceed a preset compression amount when the pressing portion presses the roller. The driving unit drives and rotates one of the fixing roller and the pressure roller in a state where the compression amount is restricted.

摘要： A fixing device includes a first opposed body and a second opposed body pressed against the first opposed body. A resilient member exerts a resilient bias to the second opposed body that presses the second opposed body against the first opposed body. A lever assembly is swingable to move the second opposed body against the resilient bias exerted by the resilient member between at least a reduced pressure position where the second opposed body presses against the first opposed body with reduced pressure therebetween and an enhanced pressure position where the second opposed body presses against the first opposed body with enhanced pressure therebetween. A resistance applier engages the lever assembly to exert drag on the lever assembly when the lever assembly moves the second opposed body from the reduced pressure position to the enhanced pressure position.

摘要： A sheet pressing device includes plurality of pressing members and a support member. The plurality of pressing members is provided on a downstream side in a discharging direction of fixing unit which carries out a fixing treatment over a sheet having an unfixed image transferred thereonto along the discharging direction. The plurality of pressing members presses both ends of the sheet in a direction along a surface of the sheet carried out the fixing treatment by the fixing unit and in a direction crossing the discharging direction. The support member supports the plurality of pressing members movably in such a direction as to approach or separate from the sheet when the sheet passes through the sheet pressing device.

摘要： A fixing device includes an endless flexible belt, a stationary pad, a rotary pressure member, and a reinforcing member. The endless flexible belt is looped into a generally cylindrical configuration extending in an axial direction thereof for rotation in a rotational, circumferential direction thereof. The stationary pad is stationarily disposed inside the loop of the belt. The rotary pressure member is disposed parallel to the belt. The rotary pressure member presses against the stationary pad via the belt to form a nip therebetween. The reinforcing member is stationarily disposed in contact with the stationary pad inside the loop of the belt for reinforcing the stationary pad. The stationary pad includes two or more contact portions spaced apart from each other in the conveyance direction, each generally extending in the axial direction of the looped belt and protruding toward the reinforcing member to contact the reinforcing member.
