摘要： This fixing device has a fixing portion coming into contact with one face of a sheet, a plurality of drive portions coming into contact with the other face of the sheet to nip the sheet with the fixing portion, and a control portion for driving a plurality of the drive portions. The drive portions are placed in a direction orthogonal to a transportation direction of the sheet. The control portion controls driving of the drive portions independently of each other so that a speed difference may be imparted to the transportation speed of the sheet in the direction orthogonal to the transportation direction of the sheet. Thereby, it becomes possible to stabilize passing posture of the sheet S, and therefore to decrease wrinkling and image failure attributed to the passing posture of the sheet.

摘要： A first pad has a first nip forming surface which extends in a direction X. An angle formed between an end portion of the first nip forming surface and an XZ plane is smaller than an angle formed between a central portion of the first nip forming surface and the XZ plane, where the XZ plane is formed on a downstream side of the first nip forming surface. Thereby, a fixing device is provided which suppresses generation of wrinkles on a recording material when the fixing device fixes toner on the recording material and conveys it.

摘要： A belt-type fixing device is provided by which driving torque for a fixing belt can be reduced.The belt-type fixing device has the fixing belt wound around a heating roller and around a nip forming member, and has a pressurizing roller that is in pressure contact with the nip forming member with the fixing belt interposed between. A surface of the nip forming member that is opposite to the pressurizing roller is configured as a curved surface extending along an outer circumferential surface of the pressurizing roller so that a pressure distribution in a fixing nip is made generally flat with respect to a paper feeding direction. By rotational drive of the pressurizing roller, the fixing belt is rotated while being slid on the nip forming member. Contact area between the fixing belt and the nip forming member outside the fixing nip is smaller on nip entrance side than on nip exit side.
