Patent ID: 8682212

Claim:
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; a push-in force giving portion, which is disposed downstream of a downstream side end of the resistance force giving portion in the push-in direction, for giving a push-in force to a push-in force receiving portion of the cartridge support member in the push-in direction by contacting the push-in force receiving portion; and a main body side positioning portion configured to position the cartridge support member in the inside position with respect to the apparatus main body, the main body side positioning portion positioning the cartridge support member with a gap between the push-in force receiving portion and the push-in force giving portion.
