ABSTRACT:
The present invention relates to an electrophotographic color image forming apparatus using a tandem-drum development, an indirect image-transfer method, and a vertical sheet supply path. An intermediate image-transfer member is angled relative to a horizontal line such that a rear side of the intermediate image-transfer member away from a recording sheet is lifted and a front side of the intermediate image-transfer member closer to the recording sheet is lowered. Further, image creating mechanisms of the tandem-drum development are aligned and arranged in parallel to a moving image transfer bed of the intermediate image-transfer member, such that one of the image creating mechanisms firstly forming an image faces the rear side of the moving image transfer bed and another one of the image creating mechanisms lastly forming an image faces the front side.
