Abstract
A color electrophotographic apparatus which can achieve full color image reproduction with one-pass developing is disclosed. According to the present invention, a flexible photoconductor is formed as an endless belt driven by a set of rollers. Developers of various colors are projected onto a surface of the photoconductor from a plurality of developing units. After the projection of the color developers is achieved, the resultant full color toner image is transferred to a recording medium. The toner image is then fused onto the recording medium, thereby reproducing the full color image. The flexible photoconductor is arranged to have a planar surface between the two rollers, with the four optical exposure units positioned to direct four parallel beams of light in a direction perpendicular to the planar printing surface of the photoconductor. Each of the aligned exposure units have an associated line memory register and at least one shift register for horizontally aligning the lines of information from each exposure unit.
