Abstract:
1. A color electrophotographic image forming apparatus for forming an image on a recording material, wherein a plurality of cartridges is detachably mountable to a main assembly of said image forming apparatus, said apparatus comprising: a cartridge supporting member for supporting the cartridges, said cartridge supporting member being movable between a set position, inside the apparatus main assembly, in which the cartridges are to be located at an image forming position in which the cartridges effect image formation, and an outside position, outside the apparatus main assembly, in which the cartridges are mountable to and demountable from said cartridge supporting member; a driving source; a driving member provided at a position in which said driving member opposes said driving source through said cartridge supporting member in a state in which said cartridge supporting member is located at the set position; a first driving force transmission member for transmitting a driving force of said driving source; a second driving force transmission member provided at a position in which said second driving force transmission member opposes said first driving force transmission member through said cartridge supporting member in the state in which said cartridge supporting member is located at the set position, wherein said second driving force transmission member transmits the driving force to said driving member; and a third driving force transmission member provided to said cartridge supporting member, wherein said third driving force transmission member is, in the state in which said cartridge supporting member is located at the set position, connected to said first and second driving force transmission members to transmit the driving force of said driving source to said driving member, wherein when said third driving force transmission member is connected to said first driving force transmission member, at least one of said third and first driving force transmission members is swingably provided, and wherein when said third driving force transmission member is connected to said second driving force transmission member, at least one of said third and second driving force transmission member is swingably provided.
