摘要： PROBLEM TO BE SOLVED: To correct the misregistration of an image in a direction crossing the conveying direction of a recording medium.SOLUTION: A control unit 103 calculates ΔT=T2-T1. In accordance with the value of ΔT, the control unit 103 calculates a variation showing a positional change of a patch image pt in a period where the patch image pt moves from a primary transfer position to the position of a patch image detection sensor 20. Next, based on the calculated variation, the control unit 103 predicts a value showing in which direction and how far a normal image 22 is deviated in a period where the normal image 22 moves from the primary transfer position to a secondary transfer position, and then calculates a correction amount for the skew of an intermediate transfer belt 2 in accordance with the predicted value. Based on the calculated correction amount, the control unit 103 controls the posture of an adjusting mechanism 104 so that the conveying direction of the intermediate transfer belt 2 becomes close to the original conveying direction of that at the secondary transfer position.

摘要： PROBLEM TO BE SOLVED: To provide a technology of suppressing degradation in formation positioning accuracy of an image to a recording medium. SOLUTION: The time when toner images reach a transfer device 20, which is calculated on the basis of timing of forming toner images on a transfer belt 15 in image forming units 10Y, 10M, 10C, and 10K, is compared with the time the toner images reach the transfer device 20, which is calculated, on the basis of an output from an image position detection sensor 44 that optically detects the toner images formed on the transfer belt 15. When there is a predetermined relation among them, the position of an image to be formed on paper is adjusted, by using the latter information to control paper conveyance, the subsequent image formation timing, or the subsequent image forming processes. When there is no predetermined relation among them, the position of an image to be formed on paper is adjusted, by using former information to control paper conveyance, the subsequent image formation timing, or the subsequent image forming processes.

摘要： PROBLEM TO BE SOLVED: To accurately detect a detection pattern irrespective of a reflectance of a base where the detection pattern is formed. SOLUTION: The position of the detection pattern formed with magnetic toner is detected through the use of magneto-optical effect as a phenomenon that, when linearly-polarized light is emitted and reflected by a magnetized object, the light is reflected while changing the polarization state thereof. Consequently, the detection pattern is stably detected with less erroneous detection, irrespective of variation in the reflectance and shape of the base of the irradiation surface or in the optical density of the detection pattern.

摘要： PROBLEM TO BE SOLVED: To suppress the occurrence of defective images even if screen processing is executed after a positional deviation of pixels is corrected by image processing. SOLUTION: An image 1 has been screen-processed in a line in a direction at an angle of 45° to the main scanning and sub-scanning directions. After shifting up the image 1 to correct a declining skew, the arrangement of the pixels is as shown by an image 1u, which causes black lines. In order to eliminate the black lines, a pixel P1 (black pixel) arranged at a certain position in the image 1u is replaced by (inverted into) a white pixel as shown in the image 1p, thus fading the black lines.
