摘要： A fixing device for fixing on a recording material a toner image formed on the recording material includes a flexible sleeve including a resinous base layer, a parting layer and an adhesive layer for bonding the base layer and the parting layer; a heater contacted to an inner surface of the sleeve; a pressing member for forming a nip, in which the recording material on which the toner image has been formed is nipped and conveyed, between itself and the sleeve to which the heater is contacted; a voltage applying member for applying a voltage, of a polarity identical to a polarity of toner; and a grounding member, contactable to the recording material in a nipped state in the nip, for grounding the recording material. In a thickness direction of the layers, an electric resistance of the adhesive layer is larger than that of the parting layer and the electric resistance of the parting layer is larger than that of the base layer. The voltage applying member applies the voltage to the sleeve in contact with the base layer.

摘要： The present invention relates to an image heating apparatus in which a nip portion is formed by a heating unit, which includes a flexible sleeve and a heater, and a pressure roller. The position of the heating unit is appropriately maintained by pressing the heating unit against the pressure roller using a pressure member so that the heating unit can contact two or more portions of a downstream side rim of a groove arranged on a frame that holds the heating unit, even when the pressure roller is rotated.

摘要： An image-forming apparatus includes a pre-charge exposure device which removes electric charge from a photoconductor drum to increase a potential contrast between the surface of the photoconductor drum and the surface of a charge roller in an upstream region of a nip region between the photoconductor drum and the charge roller in the rotating direction of the photoconductor drum, so that toner accumulating in an upstream region of the nip region in the rotating direction of the photoconductor drum is restrained and prevented from being discharged onto an image-forming region. When the toner accumulating in the upstream region of the nip region in the rotating direction of the photoconductor drum is to be discharged onto a non-image-forming region, the pre-charge exposure device is turned off so that the potential contrast decreases.

摘要： An image forming apparatus is disclosed in which a specific toner is used, and a transferring means has a transfer roller which is in contact with the surface of an electrostatic image bearing member and rotates when the electrostatic image bearing member rotates. The toner is comprised of particles which have a weight average particle diameter of 4 to 12 &mgr;m, and in a circularity distribution for particles 3 &mgr;m or more in circle-equivalent diameter which are included in the toner, particles having a circularity of 0.90 or more account for 90% by number or more.
