摘要： An image forming apparatus includes an image bearing belt of a multi-layer structure, a toner image forming device, a nip forming device a transfer power source, an environment-condition detector, and a controller. The toner image forming device forms a toner image on a surface of the image bearing belt. The transfer power source outputs a transfer bias including a superimposed voltage, in which a direct current voltage is superimposed on an alternating current voltage to transfer the toner image from the image bearing belt onto a recording medium at a transfer nip. The environment-condition detector detects an environment condition. The controller controls the transfer bias output from the transfer power source to perform a bias switching process to switch the transfer bias between a transfer bias including the superimposed voltage and a transfer bias including a direct current voltage based on a detected result of the environment-condition detector.

摘要： An image forming apparatus includes an image bearer, a toner image forming device, a plurality of image density detectors, and a controller. The plurality of image density detectors are disposed at predetermined intervals opposite the image bearer in a width direction of the image bearer. The controller causes the toner image forming device to form toner image patterns having an identical density at the plurality of positions on the image bearer and the plurality of image density detectors detects a density of the toner image patterns. Based on the detected density of the toner image patterns, the controller identifies multiple cyclic fluctuations of the density of the toner image patterns and adjusts an image forming condition based on the multiple cyclic fluctuations of the density of the toner image patterns to decrease an amplitude caused by the multiple cyclic fluctuations of the density of the toner image patterns.

摘要： An image forming apparatus includes an image forming device, an image density detector, and a processor. The processor controls the image forming device to form a first test toner image, and controls the image density detector to detect an image density at the plurality of positions of the first test toner image. The processor adjusts an image forming condition so that the image density detected at each of the plurality of positions becomes a target image density, controls the image forming device to form a second test toner image based on the adjusted image forming condition, controls the image density detector to detect an image density at the plurality of positions of the second test toner image, determines whether a streak exists in the second test toner image based on the detected image densities, and executes a countermeasure to prevent an occurrence of the streak.

摘要： An image forming apparatus includes an image forming device, a density deviation detector, and processing circuitry. The circuitry performs a density deviation adjustment mode to: cause the image forming device to form a first image pattern having a uniform image density in the width direction on a surface of an image bearer; cause the detector to detect a first image density deviation in the width direction in the first pattern; adjust the first deviation based on a detection result of the first pattern; cause the image forming device to form a second image pattern on a surface of the image bearer after adjustment of the first deviation; cause the detector to detect a second image density deviation in the width direction in the second pattern; and correct a light intensity sensitivity in adjusting the second deviation, based on a detection result of the second pattern.

摘要： An image forming apparatus includes an image bearer, a toner image forming unit, a detector, and a controller to adjust an image forming condition based on a detection result by the detector. During a non-printing period, multiple toner patterns are formed in an end and center portions of the image bearer in a direction perpendicular to a direction in which the image bearer moves, and a smaller number of toner patterns selected from the multiple toner patterns are formed in a non-image area, in the end portion of the image bearer, during a printing period. The controller determines a target density X of the smaller number of toner patterns by X=H (a mean detected density of the multiple toner patterns formed in the end portion)×J (a predetermined reference value)/I(a mean detected density of the multiple toner patterns formed in the end portion and in the center portion).
