发明名称 Two-sided color image forming apparatus
摘要 A two-sided color image forming apparatus includes: a first and second color image forming units each having an image carrier, a plurality of imagewise exposure devices and a plurality of color developing units containing respective colored toners different from each other, provided on a periphery of the image carrier; a belt-shaped intermediate transfer body passing through the first and second color image forming units for receiving a toner image formed by the second color image forming unit, wherein the first and second color image forming units are disposed downstream and upstream of a moving direction of the belt-shaped intermediate transfer body, respectively, and; a sheet pass for conveying a recording sheet onto the belt-shaped intermediate transfer body passing through between the first and second image forming units. The two-sided color image forming apparatus further includes: a second transfer device for transferring the toner image formed by the second color image forming unit onto one side of the recording sheet through the belt-shaped intermediate transfer body; and a first transfer device for transferring directly a toner image formed by the first color image forming unit onto the other side of the recording sheet, wherein each of color image formation orders for plural color toners formed respectively by the first and second color image forming units is completely reversed to each other.
