Abstract
Among four color developing units provided in a color image forming apparatus, a black developing unit which is arranged to be the last in order of development is disposed on either one of the farthest ends of a reciprocative movement holding member in the direction of its reciprocating movement, and the developing units arranged to be the first and the third in order of development are properly disposed on the second and the third stages of the reciprocative movement holding member. Each one of these developing units is freely moved to the developing location opposite to a photoconductor by reciprocating movement of the reciprocative movement holding member in accordance with a predetermined order of development.
