摘要： An image forming apparatus includes a fixing unit for fixing a toner image on a recording sheet. In the fixing unit, a magnetic flux generator generates magnetic flux to induce heat in a fixing roller. The recording sheet having the toner image is inserted between the fixing roller and a pressure roller pressingly contacting the fixing roller. The fixing roller applies heat to the recording sheet. The pressure roller applies pressure to the recording sheet. The heat and pressure fix the toner image on the recording sheet. The magnetic flux generator is disposed to face outer and inner circumferential surfaces of the fixing roller. The magnetic flux generator is formed in a U-like or loop-like shape, and the fixing roller is placed in a gap or a loop of the magnetic flux generator. The magnetic flux generator may include a single wire.

摘要： A device configured to be heated to a temperature sufficient to fuse an image forming substance to a sheet includes a hollow roller made of a conductive material and a coil arranged in a hollow portion of the hollow roller. The coil is configured to carry an electrical current that induces a current in the conductive material of the hollow roller such that the hollow roller becomes heated so as to fuse toner to a sheet. The coil is mounted on a member that is disposed in the hollow portion of the roller. The member includes various combinations of features that permit a reliable and safe operation of the induction heating apparatus such as recess and projections formed in the member to separate respective turns in the coil, a hollow center of the member that can be ventilated with a ventilation fan, and predefined gaps being maintained between the inside surface of the hollow roller and an outer surface of the coil.

摘要： An apparatus for cleaning a photosensitive member comprising a cleaning roller formed of foamed resin which contacts the member and a pressure plate held in compressing abutment against the roller so as to extend in the direction of its forward rotation at the point of contact therebetween. Any residual powder on the photosensitive member is removed by the roller and retained in the pores formed in the roller surface. The powder retained in the pores is expelled by the resilience of the compressed surface of the roller as it is restored upon release from the pressure plate. The cleaning apparatus also comprises a system for recovering powder that is expelled from the roller surface, and a rotating helical coil disposed in a conveyance path for preventing solidification of the powder and for facilitating its conveyance.
