摘要： An image forming apparatus includes an endless belt, a pair of belt winding rollers that wind and rotate the endless belt, and a belt shift detecting device that detects a belt shift. The image forming apparatus further includes a roller end moving device that moves one end of one of the belt winding rollers around its other end in response to the detection of a belt shift to suppress the belt shift to a predetermined range, and a belt surface contacting device that pressure contacts the surface of the endless belt. The belt surface contacting device is mounted on a frame that supports a shaft of the belt winding roller to be moved so that its contacting condition does not change during the movement of the belt winding roller moved by the roller end moving device.

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.

摘要： A fixing device including a fixing belt, a drive roller and a press roller. The drive roller is configured to drive the fixing belt, and press roller is arranged so as to face the drive roller across the fixing belt, and exert pressure toward the fixing belt. The drive roller and the press roller are able to rotate so that the peripheral velocity of the drive roller is greater than the peripheral velocity of the press roller. According to the fixing device image defects, including image difference, are less likely to occur when fixing an image on a recording sheet.
