摘要： PROBLEM TO BE SOLVED: To provide a charging control device designed to suppress meaningless wear of a body to be charged. SOLUTION: The device comprises: a first alternate current determination part; a prohibition part; and a second alternate current determination part. The first alternate current determination part applies a dummy alternate current component to a charge body which gives charges to the body to be charged by superimposing and applying direct current and alternate current of current or voltage thereto at a plurality of intensities, directly or indirectly detects a direct current component of current carried from the charge body to the body to be charged, and determines an alternate current component value to be applied to the body to be charged based on the detection result of direct current component. When the detection result of current by the first alternate current determination part shows a predetermined detection result showing deterioration of the body to be charged, the prohibition part prohibits the determination of alternate current component value by the first alternate current determination part, and when the determination is prohibited by the prohibition part, the second alternate current determination part determines the alternate current component value based on information different from the detection result of direct current component instead of the first alternate current determination part.

摘要： PROBLEM TO BE SOLVED: To maintain a stable image quality over a long period, while preventing the image quality from being deteriorated caused by the discharge product by removing a discharge product deposited onto a surface of an image holding body with a simple constitution. SOLUTION: This image forming apparatus is provided with the rotatable image conveying body 2 arranged opposedly to the plurality of image holding bodies 1, and for conveying a toner image on the image holding bodies 1 directly or via a recording material S, a speed variable means 3 capable of varying independently speeds of the plurality of image holding bodies 1 in one unit or units of the number smaller than the number of the image holding bodies 1, a judging means 4 for judging the propriety of contribution to image formation out of the plurality of image holding bodies 1, and a speed control means 5 having a first speed mode for setting the speed of the image holding body 1 contributing to the image formation, as a first speed, and a second speed mode for setting the speed of the image holding body 1 not contributing to the image formation, as a second speed with a speed difference getting large with respect to the image conveying body 2, compared with the first speed, and for controlling the speed variable means 3 to select any of the speed modes in respective image holding bodies 1, based on a judged result by the judging means 4.

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus and an image forming program, for reducing misalignment between exposure positions of a first light source for exposure and a second light source for exposure, due to a difference in temperature and for reducing an image failure occurring due to light emission from the second light source for exposure. SOLUTION: The image forming apparatus includes: the first light source for exposure which is composed on a plurality of light emitting elements and exposes a first photoreceptor; the second light source for exposure which is composed of the plurality of light emitting elements and exposes a second photoreceptor; a detection means for detecting the temperature of the light sources for exposure; a calculating means for calculating the difference in temperature between the first light source for exposure and the second light source for exposure; and a control means for controlling the light emission of the first or the second light source for exposure so that the temperature difference calculated by the calculating means is reduced based on the temperature difference that is calculated by the calculating means. Thus, the misalignment in the exposure positions occurring due to the temperature difference is reduced and the image failure occurring due to the light emission by the second light source for exposure is reduced.
