摘要： An intermediate transfer drum has at least a drum main body having a volume resistivity of 10.sup.4 to 10.sup.8 .OMEGA.cm, and an insulating layer provided on an outer surface of the drum main body. A first transfer voltage applying roller is provided inside the intermediate transfer drum so as to be opposite to a photosensitive drum and so as to be in contact with an inner surface of the intermediate transfer drum. A transfer roller is provided inside the intermediate transfer drum so as to be opposite to a second transfer grounded roller and so as to be in contact with the inner surface of the intermediate transfer drum. By thus arranging an image forming apparatus wherein image formation is carried out with respect to recording paper through the intermediate transfer drum, an optimal first transfer voltage can be applied from the photosensitive drum to the intermediate transfer drum, while an optimal second transfer voltage can be applied from the intermediate transfer drum to the recording medium. As a result, the first transfer and the second transfer are individually and simultaneously carried out. Furthermore, since the intermediate transfer drum does not become large in size, it is avoidable that the image forming apparatus becomes bulkier, while the lowering of the copying speed can also be suppressed.

摘要： In the present applying mechanism, a part of a guide sheet 33 bulges (arches) away from an oil application roller 16, with respect to a vertical line S passing through the center of a pipe 31. In other words, in the present applying mechanism, a part of the guide sheet 33 has a shape of avoiding (bypassing) the oil application roller 16 that has a high temperature. With this, oil flowing on the guide sheet 33 is kept away from the high-temperature oil application roller 16. On this account, it is possible to restrain the degradation of the oil flowing on the guide sheet 33 on account of the heat from the application roller.

摘要： Since the paper entry guide is disposed below and in close proximity to a fixing belt, the leading edge of recording paper can become wavy or curled when operated in a high temperature, high humidity environment or when printing on the reverse side of the paper in double-sided print mode, and this has lead to the problem that the leading edge of the recording paper after transfer is not properly inserted in the narrow spacing between the paper entry guide and the fixing belt, resulting in a recording paper jam. A fixing device comprises a fixing belt stretched around a heating roller with a heat source contained therein and a fixing roller, a pressing roller for pressing the fixing roller from below via the fixing belt, and a paper entry guide disposed below and in close proximity to the fixing belt and upstream of a nipping portion composed of the fixing belt and the pressing roller. The paper entry guide is pivotably supported on a fulcrum. A solenoid is provided at the upstream side of the paper entry guide, and a return spring is disposed above the paper entry guide. The solenoid, when in the ON state, pulls a plunger to its lowermost position against the spring force of the return spring, and thereby rotates the paper entry guide in the clockwise direction about the fulcrum to maintain spacing with respect to the fixing belt.

摘要： In one embodiment, a fixing apparatus is configured of a pressing portion for causing the pressure roller to enter a pressure applied state by applying bias, a switching portion for causing the pressing portion in the pressure applied state to enter a pressure released state by causing a cam to rotate forward, a pressure state detection portion for detecting the pressure released state, and a control portion for, when shifting from the pressure applied state to the pressure released state, turning forward the cam of the switching portion in the pressure applied state and stopping the cam after the pressure state detection portion detects the pressure released state. If the cam is turned forward with respect to the switching portion for a certain time period, but the pressure state detection portion does not detect the pressure released state, the control portion performs forward rotational direction retry control.

摘要： A fixing control section of a fixing apparatus according to the present invention includes an end section priority temperature control mode. In the end section priority temperature control mode, the fixing control section temporarily turns off a main heater heating a center section of a fixing roller among a plurarity of heaters disposed inside the fixing roller in a case where a surface temperature of the end section of the fixing roller has reached a preset upper-limit fixing temperature, even if the surface temperature of the center section of the fixing roller is lower than a preset fixing temperature. As a result, destruction of the fixing roller can be prevented by a simple arrangement in the fixing apparatus which includes a plurarity of the heaters disposed inside the fixing roller.

摘要： In a fixing apparatus of the present invention, an end section fixing control temperature changing section selects an end section fixing control temperature in accordance with the number of paper sheets that have been processed in one continuous printing process. A sub-heater on/off determining section turns on or off a sub-heater in accordance with a temperature detected by an end section temperature sensor and the end section fixing control temperature selected by the end section fixing control temperature changing section. This prevents the occurrence of fixing failure even in continuous printing with respect to large-size paper sheets in an arrangement in which a temperature sensor is disposed outside a maximum-size sheet passing region at an end section of a fixing roller and controls energization of a heater which is disposed corresponding to the end section of the fixing roller in accordance with a temperature detected by the temperature sensor.

摘要： In a fixing device including (i) an external heat belt which abuts against a surface of a fixing roller so as to heat the fixing roller and (ii) a cleaning member which abuts against the external heat belt, a fixing temperature, which is a surface temperature of the fixing roller during a fixing process, is set per group into which recording media to be subjected to the fixing process are divided according to their widths in a direction of a rotary axis of the fixing roller, in such a way that the fixing temperature is set to a lower temperature for a group of narrower widths. This makes it possible to prevent a reduction in releasability of the fixing roller caused by a material, which is scraped off from the external heat belt by the cleaning member and then adhered to the fixing roller, thereby preventing the high-temperature offset.
