摘要： An image forming apparatus includes a fixing device. The fixing device includes a rotatable endless fixing member, a nip forming member arranged inside the fixing member, a pressing member in contact with the nip forming member via the fixing member, and a heating source configured to heat the fixing member. When an abnormality occurs in at least one of the fixing device and other devices included in the image forming apparatus, a rotation of the fixing member is stopped prior to stopping a rotation driving of a discharging unit and, after stopping, the fixing member is controlled to rotate.

摘要： An image forming apparatus includes a fixing unit and a fixing process managing system. The fixing process managing system, including a mode switchover unit, controls a time mode and a temperature mode for heating a fixing member. In the time mode, the fixing unit is determined to be ready for a fixing process when a given time elapses after activation of the image forming apparatus. In the temperature mode, the fixing unit is determined to be ready for a fixing process when a temperature of the fixing member attains a given reference temperature after activation of the image forming apparatus. The mode switchover unit selects between the temperature mode and the time mode. The fixing process managing system selects the temperature mode instead of the time mode when a supply amount of electrical power to the fixing unit is determined to be below a required electrical power supply level.

摘要： An image forming apparatus of the present invention includes a latent image forming device for forming a latent image on an image carrier and a developing device for developing the latent image with toner to thereby form a corresponding toner image. The surface of an intermediate image transfer body is movable and includes an high-resistance layer having a volume resistivity of 1010 &OHgr;·cm or above. A primary image transferring device transfers the toner image from the image carrier to the intermediate image transfer body. Secondary image transferring device transfers the toner image from the intermediate image transfer body to a sheet. A polarization uniforming device uniforms, at the beginning of an image forming operation, polarization left in the high-resistance layer while preserving the polarity of the polarization after the surface of the intermediate image transfer body has started moving, but before the toner image is transferred from the image carrier to the secondary image transfer body.

摘要： In a multicolor image-forming apparatus having a photoelectric sensor for detecting the amount of toner of an unfixed toner image adhering onto a photosensitive element, and a toner density sensor for detecting the density of a developer in a developing machine to form a multicolor image by overlapping the toner images having a plurality of colors, a color-balance control method comprises the steps of correcting a setting value of an output of the toner density sensor of the developing machine in accordance with the change in amount of toner adhering onto a photosensitive element detected by the photoelectric sensor with respect to a high density section; setting an allowable range of the toner density in advance in the developing machine with respect to the toner having at least one color; setting the amount of toner adhering onto a photosensitive element of the at least one color as a reference when the toner density is changed outside the allowable range; and correcting the amount of toner adhering onto a photosensitive element of the other color in accordance with the reference. With respect to a half-tone section, the output of the photoelectric sensor may be corrected by controlling the exposure amount. With respect to the high density section, the output of the toner density sensor may be corrected in a predetermined way when the toner density is changed.

摘要： A fixing device includes a fixing rotator and a slider that slides over the fixing rotator. A cam presses the slider against the fixing rotator. The cam includes a cam rear disposed opposite a rear end of the fixing rotator in an axial direction thereof and a cam front disposed opposite a front end of the fixing rotator in the axial direction thereof. A controller rotates the cam to a first slide position where the cam rear presses the slider against the fixing rotator, a second slide position where the cam rear and the cam front press the slider against the fixing rotator, a third slide position where the cam front presses the slider against the fixing rotator, and an isolation position where the cam rear and the cam front do not press the slider against the fixing rotator.

摘要： When calculating an actual turn-on duty based on a required duty according to a feedback control, the actual turn-on duty is corrected using a correction table or a correction conversion formula such that a required turn-on duty and the actual turn-on duty coincide with each other. A fixing heater is controlled according to the corrected actual turn-on duty.
