摘要： An image forming apparatus forms high precision full color image by correcting the adhesion quantity of an image visualizing agent and a position shift of a visible image while performing printing process. The image forming apparatus includes an intermediate transfer unit; plural photoconductors; plural charging units; plural exposure units; plural developing units; plural first transferring units; and plural second transferring units. The intermediate transfer unit has a correction pattern image formed in a region outside a predetermined maximum document region in a direction perpendicular to the moving direction. A detector in the intermediate transfer unit detects the correction pattern image. A correction controller performs correcting, based on detection results of the detector, setting values of one or more of the charging units, the exposure units, and the developing units when a region corresponding to an interval between the visible images passes a position beneath one of the units.

摘要： In an electrophotographic apparatus, regions having at least three different potential levels Vc, Vw, and Vr are formed on a photosensitive member by using an exposing device, and developing processes respectively using colored particles of different kinds are performed by normal development and reversal development on two potential levels Vc and Vr excluding the intermediate potential level Vw. The apparatus has an auxiliary exposing unit for forming a fringe development preventing potential in an edge of an image forming region in order to prevent fringe development from occurring. The auxiliary exposing unit sets an auxiliary exposure amount by performing pulse-width modulation on a laser driver.

摘要： In a two-color image forming apparatus, correction exposure of creating an area having a potential between an image area potential and a white area potential is made for a decided white area on the periphery of the image area. A potential difference between the image area and white area is reduced to attenuate an edge effect, thereby preventing the fringe development. This is accomplished by varying the light amount for the white areas of the intermediate potential areas as a function of the following: surface potentials measured, change in the developing bias voltage and rotating speed of a developing roll, adjustment of the amount of toners by a toner sensor, changing the resistance of a developer, and/or development of raster image processing.

摘要： An electrophotographic printing apparatus using electric potential dividing development processing without the occurrence of primary fringe and fringe caused by auxiliary exposure has reverse electric fields causing primary fringe and fringe caused by auxiliary exposure adjusted to be nearly equal to each other. The auxiliary exposure is applied to an area surrounding one image, and an electric potential of an intermediate electric potential zone is brought close to a bias electric potential of another image which is not subjected to auxiliary exposure. Further, a white portion to produce a reverse electric potential therein at the rear end of an electric potential portion to be developed with toner, relative to a rotating direction of a developing roller, is exposed with a light intensity forming an electric potential between an electric potential developing an image with toner and the intermediate electric potential, and portions at the front end and the sides are exposed with a light intensity forming the intermediate electric potential.

摘要： An image forming apparatus includes an image forming device to form an image on an image bearer and circuitry configured to accept, from a user, an input of a density level selected from a plurality of different density levels and control an image forming condition under which the image forming device forms the image. The circuitry is configured to correct density unevenness of the image formed on the image bearer by the image forming device and correct the density unevenness of the image at the density level accepted. The density unevenness is unevenness appearing in a main scanning direction orthogonal to a direction of conveyance of the image bearer during image formation.

摘要： An image forming apparatus includes an image bearer to bear a black toner pattern formed with a black toner image under an increased exposure amount and an increased developing bias. A first optical sensor detects an amount of reflection light reflected by the black toner pattern on the image bearer. The first optical sensor includes a light-emitting element to emit light toward the black toner pattern on the image bearer and a light-receiving element to receive the reflection light reflected by the black toner pattern on the image bearer. A toner adhesion amount converter converts the amount of the reflection light detected by the first optical sensor into a toner adhesion amount of toner adhered to the image bearer and adjusts an image density according to the toner adhesion amount.
