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： In an image forming apparatus, the overall length of a heat generating resistor is set longer than the width of a recording paper, which is the greatest of widths of standard size recording papers that can be used on the image forming apparatus. An electrical resistance of an edge area of the heat generating resistor per unit length is set smaller than that of a center area of the heat generating resistor. The position of a boundary between the center area and the edge area is set so that the position of the side edge of the recording paper whose width is the greatest exists within the edge area and so that if the recording paper having the second greatest width is fed by a one edge-aligned paper feeding method, the position of the side edge of a recording paper whose width is the greatest of the widths of the standard size recording papers that can be used on the image forming apparatus except the width of the recording paper that is the greatest thereof is set at a position within the center area.

摘要： An image forming apparatus includes a toner carrying member for carrying a toner; an image carrying member, contacting the toner on the toner carrying member, on which a toner image is to be formed with the toner; and an electrode portion provided at an opposing position in which the electrode portion opposes the toner carrying member via the image carrying member interposed therebetween. The toner image is formed on the image carrying member by changing a value of a voltage, on the basis of image information, applied to the electrode portion. The toner carried on the toner carrying member and the image carrying member contact each other in a toner contact area. The toner is moved between the toner carrying member and the image carrying member in a toner movement area by changing the value of the voltage applied to the electrode portion. The toner movement area is present downstream of the toner contact area with respect to a movement direction of the image carrying member.

摘要： An image forming apparatus includes a toner carrying member for carrying a toner; an image carrying member on which a toner image is formed with the toner; and a plurality of divided electrode portions provided at a position in which the electrode portions oppose the toner carrying member via the image carrying member interposed therebetween. The electrode portions are supplied with a voltage on the basis of image information to move the toner between the toner carrying member and the image carrying member thereby to form the toner image. The electrode portions includes a first electrode portion for forming an image portion and a second electrode portion, adjacent to the first electrode portion, for forming a non-image portion. The image forming apparatus further includes a controller for variably controlling at least one of potential differences |Vp−Vt| and |Vt−V0| depending on the image information, where a potential of the toner carrying member is Vt, a potential of the first electrode portion is Vp and a potential of the second electrode portion is V0.
