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.

Claims9

Dependent claims

An electrophotographic image forming apparatus, in which a cartridge is removably mounted to an apparatus main body to form an image on a recording medium, comprising:

a cartridge support member, which is moved, while supporting the cartridge, between an inside position, which is positioned at an inside of the apparatus main body, and is an image forming position at which the image is formed by the cartridge and an outside position which is positioned at an outside of the apparatus main body at which the cartridge is mounted and removed;
a resistance force giving portion, which is provided in the apparatus main body, for giving, when pushing-in the cartridge support member from the outside position to the inside position, a resistance force resisting an advancing of the cartridge support member in a push-in direction, the resistance force becoming larger as the cartridge support member advances in the push-in direction;
and
a push-in force giving portion, which is disposed downstream of the resistance force giving portion in the push-in direction, for giving the push-in force to the cartridge support member in the push-in direction.
