摘要:
In a toner image fixing device, there are provided an endless belt (75) being looped up around a heating roller (70) and a conveyance roller (74), a pressure roller (80) for pressing a sheet (61) having a toner image (62) onto the heating roller (70) with the endless belt (75) intervening between the pressure roller (80) and the heating roller (70). A sensor (73) is disposed inside the loop of the belt (75) so as to come in contact with the heating roller (70), for detecting the temperature of the heating roller (70). The fixing temperature for the toner image (62) is controlled on the basis of the temperature of the heating roller (70) detected by the sensor (73) The pressure roller (80) produces a first nip with the heating roller (70) and also a second nip with the belt (75).
摘要:
An image forming apparatus is equipped with a registering device to make a copy paper temporally waiting before the copy paper is conveyed to an image forming section so that the image formation on the copy sheet is in synchronization with the working of the image forming section. When the copy paper is kept waiting, an electric resistance of the recording member is measured. An image forming condition is determined in accordance with the measurement result.

摘要:
A fixing apparatus includes: a cylindrical heat roller having a heating resistor layer on an inside surface thereof; a pressure member in pressure contact with the cylindrical heat roller; and a pair of electrodes provided in the cylindrical heat roller for supplying electricity to the heating resistor layer so that the heating resistor layer generates heat. Both ends of the cylindrical heat roller are formed so as to restrain radiating heat in the cylindrical heat roller from openings at the both ends of the cylindrical heat roller.
