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.
