Electrophotographic color image forming apparatus with movable cartridge carrying member and associated electrical contacts

An electrophotographic image forming apparatus for forming an image on a recording material, said electrophotographic image forming apparatus comprising:

• a main assembly frame;
• a belt member provided inside said main assembly frame;
• a movable member, movably supported by said main assembly frame, for supporting and moving a plurality of cartridges, said movable member being movable between (i) a first position in which electrophotographic photosensitive members carried on said movable member are contacted to said belt member and latent image can be formed on said electrophotographic photosensitive members, and (ii) a second position in which said electrophotographic photosensitive members are spaced from said belt member;
• and
• a plurality of main assembly side electrical contacts provided inside said main assembly frame,
• wherein said belt member is disposed upstream of said movable member with respect to a movement direction of said movable member from the first position to the second position, and
• wherein said main assembly side electrical contacts are electrically connected with cartridge side electrical contacts provided on associated cartridges carried on said movable member by movement of said movable member from the second position to the first position, and
• wherein said main assembly side electrical contacts are electrically disconnected from said cartridge side electrical contacts by movement of said movable member from the first position to the second position.
