Abstract:
1. An image forming apparatus comprising: a single or a plurality of image carriers; means for rotating said single or said plurality of image carriers; image forming means for forming a plurality of images on said single or said plurality of rotating image carriers; first image transferring means for transferring the images from said single or said plurality of rotating image carriers to a first transfer body driven by a first drive means so as to move through a first image transfer position corresponding to said single image first image transferring means for transferring the images from said single or said plurality of rotating image carriers to a single or a plurality of first image transfer bodies driven by a first drive means so as to move through a first image transfer position corresponding to said single image carrier and said single first image transfer body located where said single first transfer body is adjacent to said single image carrier or through plural first image transfer positions corresponding to said plurality of rotating image carriers and said single first image transfer body or said plurality of first image transfer bodies where said single first image transfer body or said plurality of said first image transfer bodies are adjacent to said plurality of rotating image carriers; second image transferring means for transferring resulting images from said first single image transfer body or said plurality of said first image transfer bodies to a second transfer body driven by a second drive means to move through a second image transfer position where said second image transfer body is adjacent to said first single image transfer body or through a plurality of second image transfer positions where said second image transfer body is adjacent to said plurality of said first image transfer bodies, wherein said second image transfer body comprises a roller; third image transferring means for transferring the images from said second image transfer roller to a recording medium being driven by a third drive means to move through a third image transfer position where said recording medium is adjacent to said second image transfer roller; means for making radiuses and angular velocities of said single or said plurality of image carriers equal to a radius and an angular velocity of said second image transfer roller; and means for making a position on an image carrying surface of each image carrier present where a given pixel is to be formed and a position on a second image transfer surface of said second image transfer roller where said given pixel is to be formed identical in an angle at which an eccentricity angle position has a greatest value.
