摘要： An image forming apparatus of the present invention includes a developing device bifunctioning as a cleaning device for collecting toner grains left on a photoconductive drum after the transfer of a toner image from the drum to a paper sheet or similar image transfer medium. In the event of toner collection, a DC voltage is applied that causes the residual toner to move from the drum toward a developing sleeve. A main-pole magnet generates, at a position where the developing sleeve faces the drum, a magnetic field of between 100 mT and 200 mT in a direction normal to the surface of the sleeve.

摘要： A fixing device for forming a toner image formed on a recording medium includes a heat roller accommodating a halogen heater. The halogen heater includes a glass tube formed of transparent quartz and provided with a wall thickness of 0.8 mm or below to increase transmission thereof. The increased transmission reduces a heat loss ascribable to the glass tube at the time of warm-up of the fixing device. The heat roller has such a thermal capacity that it can be warmed up in 10 seconds or loss. The glass tube is filled with inactive gas whose major component is krypton or xenon. A tungsten filament accommodated in the glass tube has its diameter reduced in order to implement a color temperature of 2,500 K or above. An image forming apparatus using the fixing device is also disclosed.

摘要： A bias voltage-applying unit applies a bias voltage to an insulating toner that includes an electric charge, by making a contact with the insulating toner. A light irradiating unit irradiates the insulating toner with a light. An electric-charge control unit controls an electric charge amount of the insulating toner by causing an optical switch phenomenon in which an electrostatic charge amount of the insulating toner changes, by irradiating the insulating toner with the light using the light irradiating unit while applying the bias voltage to the insulating toner using the bias voltage-applying unit.

摘要： A fixing apparatus includes a fixing member to be heated and a pressure-contacting member for pressure contacting the fixing member. The fixing apparatus directs and conveys a recording member through a nip formed between the fixing member and pressure applying member in such a manner that a toner image carried on a recording member contacts the fixing member in order to be fixed thereto with heat and pressure. The fixing apparatus is configured to direct a tip margin of the recording member toward the pressure applying member across a virtual linear extension line drawn from a downstream end to upstream end of the nip when only the tip margin exits from the nip. A fixing member side separation device may be separately provided from the surface of the fixing apparatus so as to separate the recording member exiting from the nip. A gap formed between the downstream end of the nip and the tip of the fixing member side separation device is set smaller than the width of the tip margin.
