    摘要: An image heating apparatus includes a flexible sleeve; a heater contacted to an inner circumferential surface of the sleeve; a pressing roller for forming a nip, between itself and the sleeve contacted by the heater, in which a recording material is to be heated; and a supporting member for supporting the heater, the supporting member being disposed inside the heater and having an area in which the sleeve is sandwiched between the supporting member and the pressing roller at least on an upstream side and a downstream side of a heater supporting position of the supporting member with respect to a rotational direction of the sleeve. The supporting member is provided, at its surface in the area, with a plurality of recessed portions for permitting passage of a lubricant. The recessed portions are provided only in an area in which a predetermined maximum width sheet available in the image heating apparatus is passable.

    摘要: An output of a DC high voltage source is supplied as a bias to a heat fixing apparatus. An output of the DC high voltage source is divided by resistors, and a divided output is supplied as a DC bias to a charging apparatus. A feedback circuit generates a feedback signal corresponding to a difference between the divided output and a reference voltage, for supply to the DC high voltage source thereby controlling the divided output voltage at a desired value. Such structure allows a supply of a bias voltage to the heat fixing apparatus higher than the bias voltage to the charging apparatus, thereby eliminating defects in the fixing apparatus such as a fixation tailing or an offset phenomenon. Also the charging apparatus can be given an exactly controlled bias voltage, thereby avoiding a halftone density unevenness resulting from an uneven charging.

    摘要: An image forming apparatus has an image forming unit for forming an image on a recording material, a fixing device for fixing the image on the recording material, an overlap-feed detector such as a transfer current detector for detecting an overlap-feed of the recording material conveyed to the fixing device and a set temperature controller for controlling the set temperature. The fixing device is maintained at a set temperature during an image fixing operation. The controller lowers the set temperature or stops the conveyance of the recording material when the overlap-feed detector detects the overlap feed. Accordingly, the image forming apparatus can prevent a fixing device from breaking due to an overlap-feed of a recording material.
