摘要： An image forming apparatus includes an image forming portion configured to form an image on a recording material; a fixing portion including a first rotatable member and a second rotatable member rotatable by rotation of the first rotatable member in contact with the first rotatable member and configured to fix the image on the recording material by heating the image while nipping and feeding the recording material on which the image is formed, at a nip formed between the first rotatable member and the second rotatable member; a motor configured to drive the first rotatable member; a torque detecting portion configured to detect a driving torque of the motor; and a controller. On the basis of the driving torque detected by the torque detecting means, the controller controls a degree of temperature rise of the first rotatable member immediately before the recording material enters the nip.

摘要： A fixing device includes: a cylindrical film; a nip forming member; and a back-up member for forming a nip. The nip forming member includes a projected portion. The projection amount of the projected portion is smaller in an end portion region positioned at an end portion of the projected portion with respect to a generatrix direction of the film than in a central region positioned at a central portion of the projected portion with respect to the generatrix direction, at least a part of the end portion region being inside a feeding region of a maximum-sized recording material usable in the fixing device. With respect to the recording material feeding direction, the width of the part of the projected portion inside the nip is broader in the end portion region than in the central region.

摘要： An image forming apparatus includes a fixing unit having a rotating member with a surface layer, a pressing member that forms a fixing nip portion to sandwich and to transport a recording material with the rotating member, and a heater that heats the rotating member. A rotating member temperature sensor detects a temperature of the rotating member, and a wearing amount acquisition portion acquires a wearing amount of the surface layer of the rotating member. The wearing amount acquisition portion acquires the wearing amount corresponding to the temperature detected by the rotating member temperature sensor, and acquires the wearing amount per recording material. The wearing amount per recording material is different depending on the temperature detected by the rotating member temperature sensor. In addition, a control temperature setting portion sets a control temperature of the heater according to the wearing amount.
