摘要： PROBLEM TO BE SOLVED: To suppress color shift caused on recording material by controlling rotational speed of a resist roll based on recognized state and degree of the color shift. SOLUTION: In the image forming apparatus, when the rotational speed of the resist roll is high to push paper, a pattern image PY is seen on a trailing edge side (third area R3) of first paper P1 as shown in Fig.(A). Also, the pattern image PY is seen on a leading edge side (first area R1) and a trailing edge side (third area R3) of second paper P2. A controller recognizes the state (position (area) where color shift occurs) and the degree (extent) of the color shift based on information input from a user through UI. Thereafter, the controller changes the rotational speed of the resist roll based on the recognized state and degree of the color shift. For example, when the state of the color shift is the one as shown in Fig.(A), the controller performs setting to decrease the rotational speed of the resist roll. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To enlarge a correction amount when correcting the relative position between a print medium and an image on the relative medium toward a direction perpendicular to a conveying direction which is a direction on the print medium for conveying the print medium to a printing position. SOLUTION: A resist roller 26 is moved in the direction which is the direction on a form and nearly perpendicular to the conveying direction of the form by a side shift mechanism, and then the alignment in the main scan direction is corrected. The position of image is moved in the direction which is the direction on the form nearly perpendicular to the conveying direction of the form by delaying or bringing forward the timing of an optical writing to a photosensitive material drum 4 by an exposure system 5, and then alignment in the main scan direction is corrected. The correction is performed at once by the same image formation. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image forming device capable of correcting the color shift of toner images of each color without lowering productivity.
SOLUTION: A magnetic head 12 forms magnetic latent images according to images on a magnetic drum 10. Further, a developing device 14 develops the magnetic latent image formed by the magnetic head 12 to the toner images visualized with magnetic toners of respective colors. Furthermore, the toner images of the respective colors are transferred onto the intermediate transferring body 16 and the color image is formed. In addition, a control section 48 corrects the color shift of the toner images of the respective colors by changing the transferring positions or the transfer timings of the toner images based on the color shift amount of the images transferred to the intermediate transferring body 16. Thus, the color shift of the toner images of the respective colors can be corrected without lowering productivity because there is no need to rewrite the magnetic latent images formed on the surface of the magnetic drum.
