摘要： In a method and apparatus for controlling the temperature of a fixing device of the film heating type and the pressure rotary member driving type and an image forming apparatus provided with this fixing device, at the start of printing, the output of a thermistor near a heater is detected, and when the temperature difference &Dgr;T=T2−T1 between the detected temperature T1 and the fixing temperature T2 is smaller than a desired temperature T0, the raising timing of the heater is delayed. Thereby, a pressure roller is not-excessively warmed at hot start and slip can be prevented. Also, in the image forming apparatus having the film heating type fixing device, in the next printing after the lapse of a predetermined time after the termination of a printing operation, the target temperature and heater electrical energization starting timing of the fixing device are changed in conformity with the temperature of the fixing device. The apparatus has an atmospheric temperature sensor, and in the next printing after the lapse of a predetermined time after the termination of a printing operation, the target temperature and heater electrical energization timing of the fixing device during the initial rotation operation in the printing, operation are changed in conformity with the atmospheric temperature detected by the atmospheric temperature sensor and the temperature of the fixing device.

摘要： An image forming apparatus comprises a fusing device for heating and fixing an unfixed image on a recording material while feeding the recording material, reversing device for reversing the recording material after passing the fusing device. The image forming apparatus operates in a first mode in which the recording material which passed the fusing device is ejected to an ejection section directly without being reversed, and a second mode in which the recording material which passed said fusing device is ejected to an ejection section after being reversed by the reversing device. A throughput of the recording material fed and/or the fusing temperature of the fusing device in the first mode being smaller or lower during at least part of an image forming process than in the second mode. With this image forming apparatus, the recording materials can be stacked in the ejection portion with improved quality and an excessive rise of temperature in the vicinity of the ejection portion can be avoided.

摘要： In an image heating apparatus, a film has one face in sliding contact with a heater having a heat generating portion on a substrate. The other face of the film contacts a recording material bearing an image. The film moves with the recording material and the image on the recording material is heated by heat generated by the heater which is transmitted through the film. A temperature detecting element detects the temperature of the heater. The heat generating portion of the heater has a first heat generating portion and a second heat generating portion on the downstream side of the first heat generating portion with respect to the moving direction of the film. The middle of the temperature detecting element is positioned at the upstream side of the middle between the first and second heat generating portions with respect to the moving direction of the film.

摘要： In a fixing device, a core material of a fixing rotating member has two largest-diameter portions respectively located between a central portion and each end portion of the fixing rotating member, within a region where a recording material of a largest size passes, and the diameter of each core material is gradually reduced from the largest-diameter portion toward the central portion and toward the nearest end portion. The outer shape of the fixing rotating member conforms to the shape of the core material. According to this configuration, it is possible to prevent corrugation and curl of the recording material, and to provide excellent mountability of the recording material.
