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.

An electrifying device is provided at a position of upstream in a rotating direction of the photosensitive body from the primary transfer device. A control device provides control such that in a standby state prior to starting the image forming, the distance from the mark detector to the downstream mark, viewed with respect to the direction of rotation of the intermediate transfer body, is always longer than a corresponding distance of the photosensitive body from a downstream position of the electrifying device with respect to the direction of rotation of the photosensitive body to the primary transfer section.

摘要： In an image forming apparatus, toner images of respective colors are sequentially formed on an image carrier. A primary image transfer unit sequentially transfers the toner images from the image carrier to an intermediate image transfer belt one above the other, thereby producing a composite color image on the belt. A secondary image transfer unit transfers the composite color image from the belt to a sheet or similar transfer material. When the belt makes a turn without image transfer, i.e., idles, an electric field output lower than an electric field output preselected for image formation is applied to the primary image transfer unit.

摘要： In an electrostatic image forming apparatus, including a corona discharger located so as to face an image carrier on which a toner image is to be formed. When a paper or similar recording medium is brought between the image carrier and the discharger, the discharger effects corona discharge at the rear of the recording medium so as to charge the medium to a polarity opposite to the polarity of the toner image. The toner image is then transferred from the image carrier to the recording medium. A polarity switcher allows a voltage of substantially the same polarity as the toner to be applied to a discharge wire included in the discharger, and environmental sensing device allows this voltage to be changed based on temperature and humidity conditions. The apparatus is free from defective discharge and defective image transfer ascribable to the deposition of free or isolated toner on the discharger.

摘要： An image forming apparatus includes paper trays to contain and feed a recording sheet on which a toner image is transferred; status sensors to detect a storage status of the recording sheet contained in the paper trays; a sheet sensor to detect a smoothness of the recording sheet; a memory to store detection values of the smoothness detected by the sheet sensor; a fixing device to heat and press the toner image transferred onto the recording sheet and fix it onto the recording sheet; and a control circuit to determine a target fixing temperature of the fixing device based on the detection values stored in the memory. The control circuit determines the target fixing temperature for successive recording sheets depending on the detected smoothness, and resets the detection values stored in the memory to zero when the status sensors detect a change in the storage status of the paper trays.
