<P>PROBLEM TO BE SOLVED: To provide an in-line type image forming device which can reduce deterioration such as saving of a surface layer of a photosensitive body, deformation of a developing means, and a waste of a developer and avoid staining of paper without making image formation precision nor transfer material carrying precision worse. <P>SOLUTION: The image forming device having a plurality of image forming means Pa, Pb, Pc, and Pd and an image conveying body 11 is characterized by that respective image carries 1 always abut against the image conveying body 11 and contacting and leaving between a developing means 40 and the image carries 1 and driving and stopping of the developing means 40 can be switched by the image forming means Pa, Pb, Pc, and Pd; when an image is formed, all the image carriers 1 and image conveying body 11 are driven and a desired developing means 40 is selectively driven and then brought into contact with the image carriers to form the image. At the end of the image formation, the developing means 40 is made to leave the image carriers 1 and then the developing means 40, all the image carriers 1, and the image conveying body 11 are stopped from operating. <P>COPYRIGHT: (C)2003,JPO |
