Abstract:
1. An image forming apparatus comprising: a drum unit configured to be extractable from an apparatus body and including a photosensitive drum; a developing unit configured to be extractable from the apparatus body and including a developing roller that develops a toner image on the photosensitive drum; a pressing unit configured to make the developing unit movable between a pressing position at which the developing roller is pressed against the photosensitive drum and a pressing-releasing position at which the developing roller is separated from the photosensitive drum so as to release the pressing; a projection portion provided integrally with the developing unit and configured to be projected to an extraction path of the drum unit when the developing unit is located at the pressing position and to retract from the extraction path of the drum unit when the developing unit is located at the pressing-releasing position; a biasing portion configured to bias the pressing unit from the pressing-releasing position toward the pressing position; an operation portion configured to be movable between a depressing position at which the operation portion depresses the pressing unit from the pressing position to the pressing-releasing position against the bias and a retracted position at which the operation portion retracts from the depressing position; and a depression limiting portion configured to limit the depression of the pressing unit when the operation portion is located at the retracted position and to release the limitation of the depression of the pressing unit when the operation portion is located at the depressing position.
