ABSTRACT:
A movable support member which supports a plurality of developing units is moved in reciprocating motion within a range of ordinary movement, and is arranged to be movable until one of the developing units arranged on either end of the plurality of developing units in the direction of reciprocating motion is out of the range of ordinary movement. In such position, it is possible to remove and replace all the developing units because they are all positioned away from a photoconductor and a pressing means which acts to push the units toward the photoconductor. Even in such a position, a lock mechanism is actuated to lock the movable support member.
