1. An electrophotographic image forming apparatus with which a process cartridge having an electrophotographic photosensitive member is usable, said electrophotographic image forming apparatus comprising:

  • a transfer member contactable to said electrophotographic photosensitive member to transfer a toner image from said electrophotographic photosensitive member thereonto;

    a tray for carrying said process cartridge, said tray being movable between a contact position in which said electrophotographic photosensitive member is contacted to said transfer member in a state that tray carries said process cartridge and a spaced position in which said electrophotographic photosensitive member is spaced from said transfer member in the state that tray carries said process cartridge;

    a supporting member for supporting said tray for movement in a tangent line direction which is parallel with a tangent line between said electrophotographic photosensitive member and said transfer member as seen in an axial direction of said electrophotographic photosensitive member between a first position for positioning said tray at the contact position and a second position which is retracted from the first position away from said transfer member in a perpendicular direction perpendicular to the axial direction and to the tangent line and in the tangent line direction to position said tray at the spaced position;

    a portion to be engaged; and

    an engaging portion provided in said tray and engageable with said portion to be engaged to regulate movement of said tray in the tangent line direction when said tray is at the contact position, wherein said engaging portion is disengaged from said portion to be engaged after said electrophotographic photosensitive member is spaced from said transfer member by movement of said tray in the perpendicular direction in a state of engagement with said portion to be engaged, when said supporting member moves from the first position toward the second position.
