Abstract: An electrophotographic image forming apparatus, in which a drawer supporting a cartridge is mounted in an apparatus main body, and an impact when a drawer is mounted into the apparatus main body may be suppressed to prevent a developer from scattering within a developer container. The drawer supporting the cartridge is movable between an inside position in the apparatus main body and a pullout position at which the cartridge is mounted and removed. On a forward side of the inside position, a force giving portion for giving a force to the drawer in a direction opposite to a mounting direction is provided. The force giving portion gives the force gradually to the drawer along with movement of the drawer in the mounting direction. With this structure, it is possible to suppress the scattering of the developer in the cartridge caused by the impact on mounting.
