    摘要： In a fixing device of an image forming apparatus, at least one roller of a pair of rollers (14, 15) that come into pressure contact with each other is regulated so that outer diameter of the roller is 80 to 120 mm and total length of the roller (length in the axial direction) is 470 to 600 mm, and the roller is driven and rotated at the number of revolutions of 60 to 300 rpm by fitting a key groove (14c) formed at an end of the roller to a drive key (27a) provided for a drive force-transmitting shaft. Further, average thickness of core metal material (14a) of the fixing roller is regulated so that the moment of inertia in a direction of a rotational shaft of the fixing roller is 70 Kg·cm2 and less.

    摘要： The work involved in replacing the fixing lamps in a printer is made easy, and the non-operational period of the printer associated with such maintenance work is shortened. A portion of a fixing lamp is formed in a lamp cartridge which includes a first lamp holder for holding one end of the fixing lamp; a second lamp holder for holding the other end of the fixing lamp; and a protective member holding portion for holding a lamp protective member which is attached depending on necessity. The protective member holding portion is arranged around a region where the lamp holding member is placed, and, thereby, all of the plurality of fixing lamps are capable of being attached to and removed from the heating roller as a unit from one end of the heating roller.

    摘要： A toner supply control system of the electrophotographic apparatus which includes a developing unit 3 for developing with a developer composed of toner and carrier; a toner hopper 4 for storing the toner; a toner empty sensor 7 for detecting the remainder of toner in the toner hopper 4; and a toner supply drive unit 5 for conveying toner from the outside of the apparatus into the toner hopper 4. Toner is conveyed from the outside into the toner hopper 4 by driving the toner supply drive unit 5 over a predetermined period of time without stopping the operation of the electrophotographic apparatus when the toner empty sensor 7 detects over a predetermined period of time that the remainder of toner in the toner hopper 4 is small. Then the existence of an output signal outputted from the toner empty sensor 7 indicating that the remainder of toner is small is detected, and a previous signal of toner shortage is output while the developing operation of the electrophotographic apparatus is being maintained in the case of existence of the output signal, and the shortage of toner is reported to an operator in accordance with the previous signal of toner shortage.
