摘要： An image forming apparatus includes a photosensitive member; an exposure portion configured to expose the photosensitive member to light depending on image information to form a latent image on the photosensitive member; a developing portion configured to develop the latent image into a toner image with toner; and a transfer portion configured to transfer the toner image from the photosensitive member onto a recording material. The image forming apparatus changes a surface movement speed of the photosensitive member at timing prior to predetermined timing, when a moving speed of a recording material at the transfer portion changes, by a predetermined time.

摘要： An image forming apparatus for forming a toner image on a recording material includes a fixing unit and a blower unit to blow air around a roller. The fixing unit includes a tubular shape film, a heating member disposed in a space surrounded by the film, and the roller forming a nip portion with the heating member. The fixing unit heats and fixes the toner image onto the recording material at the nip portion. For printing that forms toner images on continuously conveyed recording materials where a roller surface temperature is lower than a predetermined temperature, fan stop and operation periods are set. During the fan stop period, the blower unit is stopped and an interval between preceding and subsequent recording materials is widened. During the fan operation period, the blower unit is in operation and the interval is narrower than the interval during the fan stop period.

摘要： A fixing apparatus for fixing a toner image to a recording material includes a cylindrical film, a heater configured to make contact with the film, the heater including a substrate and a heat generation resistor formed on the substrate, and a heat conduction member configured to make contact with a surface of the heater opposite to a surface thereof being in contact with the film, the heat conduction member having a higher thermal conductivity than that of the substrate, and being divided into parts in a generatrix direction of the film. The toner image formed on the recording material is fixed on the recording material by using heat of the film, and one of the parts of the heat conduction member is configured to make contact with the heater continuously from a center to an end of a heat generation region of the heater in the generatrix direction.

摘要： The image heating apparatus includes an endless belt, a roller which contacts an outer face of the belt, and a nip portion forming unit which contacts an inner face of the belt, and forms a nip portion with the roller, for nipping and conveying a recording material. The nip portion forming unit includes a component which is longer than the belt in a generatrix direction of the belt. The apparatus also includes a regulation portion provided to oppose an end face of the belt, for regulating a shift movement of the belt to the generatrix direction of the belt. The regulation portion is integrally-molded with the component. As a result, damage of the end of the endless belt can be reduced.

摘要： Provided is an image heating device that heats an image in a nip portion, including: a film; a heater; a roller that forms the nip portion with the film; a backup member; regulating members that regulate a movement of the film and move along with the backup member; and a frame that includes a guide portion to insert the regulating members and a shaft of the roller. The roller includes an elastic layer that is deformed by being pressed from a side which the film is placed, such that a distance between a rotation axis of the roller and the nip portion decreases, and that a volume of the elastic layer decreases. The guide portion guides so that the regulating members move more to a downstream side in a conveying direction of the recording material as the regulating members approach the rotation axis of the roller.
