摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of improving stability of gradation of an image.SOLUTION: In the case where a difference between a potential of a developing electrode of a developing device and an exposure potential of a photoreceptor drum of an image forming apparatus is Vdeve, and a difference between a potential of the developing electrode of the developing device and a charge potential of the photoreceptor drum is Vcf, when the image forming apparatus forms images while controlling density of the images with Vdeve, the image forming apparatus determines whether or not a contrast ratio (Vdeve/Vcf) falls within a predetermined range; and when the contrast ratio falls out of the range, the image forming apparatus increases the number of patch patterns for gradation correction and reduces an interval to create the patch patterns for gradation correction compared to the case where the contrast ratio falls within the range, so as to enhance gradation control.

摘要： PROBLEM TO BE SOLVED: To suppress a variation in toner density caused by correcting a toner density target value.SOLUTION: A control unit 21 of an image forming apparatus 2 first calculates the average value of image density of images that have already been output in determining necessity of correction of a toner density target value. The control unit 21 then calculates the average value of image density of images that are to be output. The control unit 21 then obtains a difference between the calculated two average values, and determines whether or not the difference is larger than a predetermined threshold. If the difference is larger than the threshold, the control unit 21 does not perform correction of the toner density target value, and perform correction of a gradation correction table. If the difference is equal to or less than the threshold, the control unit 21 performs correction of the toner density target value.

摘要： PROBLEM TO BE SOLVED: To suppress a change of density between images before and after the replenishment of toner, which occurs when a high density image is formed after low density images are continuously formed, and the toner amount consumed following the formation of the high density image is replenished.SOLUTION: A control part 21 of an image forming apparatus 2 calculates a toner replenishment amount corresponding to an output image, and calculates a total toner replenishment amount by adding a carryover toner replenished amount to this replenishment amount. Further, the control part 21 calculates the average image density of a group of images output in the past, and identifies a threshold value Th1 based on this average image density. When the total toner replenishment amount is calculated and the threshold value Th1 is identified, the control part 21 compares both of the values, and replenishes the toner into a toner development device 33 by the amount shown in the value of the latter when the value of the former is larger. The control part 21 calculates a difference between the value of the former and the value of the latter, and records the difference in a RAM as a carryover toner replenishment amount.
