Electrophotographic image forming apparatus

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

• an opening provided in a main assembly of the apparatus;
• an openable member movable between a close position for closing said opening and an open position for opening said opening;
• a drawer member for supporting an electrophotographic photosensitive member, said drawer member being movable in a direction crossing with a longitudinal direction of said electrophotographic photosensitive member through said opening between an inside position inside said main assembly of the apparatus and an outside position outside said main assembly of the apparatus where a cartridge can be mounted and dismounted;
• a transfer unit movable about a rotation axis disposed downstream of said electrophotographic photosensitive member with respect to a mounting direction of said drawer member from the outside position to the inside position, between a contact position in contact with said electrophotographic photosensitive member and a separation position separate from said electrophotographic photosensitive member in a state that said drawer member is in the inside position;
• and
• an interrelating member interrelating said openable member and said transfer unit with each other, wherein said interrelating member moves said transfer unit from the contact position to the separation position with movement of said openable member from the close position to the open position, and moves said transfer unit from the separation position to the contact position with movement of said openable member from the open position to the close position,
• wherein said openable member has a second rotation axis on said main assembly of the apparatus, and said interrelating member includes a first connecting portion rotatably connecting with said transfer unit and a second connecting portion rotatably connecting with said openable member, wherein when said openable member is opened, said second connecting portion is upstream of a line connecting the second rotation axis and the first connecting portion with respect to the mounting direction, and when said openable member is closed, said second connecting portion is downstream of a line connecting said second rotation axis and said first connecting portion with respect to the mounting direction.
