摘要： A heat fixing apparatus, in which a recording material, with an unfixed image passes through a fixing nip formed by a fixing member and a pressurizing member, has an electro-conductive member to be in contact with the recording material disposed downstream of the fixing nip with respect to the recording material conveying direction, wherein a bias voltage is applied to at least one of the fixing member and the electro-conductive member. As recording materials are consecutively fed, the bias voltage applied while the recording materials pass through the fixing nip portion is gradually decreased in accordance with the number of heated recording materials. Thus, smeared image trailing edge upon fixing is prevented from occurring, and the amount of toner adhering to the surface of the fixing member or the surface of the pressurizing member is reduced, so that image errors such as toner contamination are prevented from occurring.

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.
