摘要： An image forming apparatus includes an apparatus body having a cartridge accommodation portion, an opening/closing member attached to the apparatus body and being movable between a first position at which the cartridge accommodation portion is exposed to the outside of the image forming apparatus and a second position at which the opening/closing member covers the cartridge accommodation portion and an operation panel unit for operating the image forming apparatus. The operation panel unit has: a sheet portion; and a switch portion to transmit a user's operation to the image forming apparatus via the sheet portion. The sheet portion provided in the opening/closing member is disposed at such a position as to at least partially overlap the cartridge accommodation portion on an insertion/removal trajectory of the cartridge and to cover the switch portion provided in the apparatus body in a state in which the opening/closing member is at the second position.

摘要： Provided is an image forming apparatus in which a movable member comes close to an opening to cover a part of the opening in the open state of an opening and closing member. In the course of change from the open state to the state in which an entering portion enters the inside of the housing, the movable member is pressed by the entering portion to move away from the opening and the opening and closing member moves toward the opening. In the closed state of the opening and closing member, the movable member is placed in a position further away from the opening than in the open state, and the opening and closing member is in the position in which the opening and closing member covers a part of the opening while forming a gap between the opening and closing member and the housing.

摘要： The present invention provides an image forming apparatus that can facilitate a replacement of a sheet feeding portion.When a detecting portion detects that a sheet feeding cassette is mounted, a controller controls a driving portion in such a manner as to lift a sheet supporting plate for the mounted sheet feeding cassette. When the detecting portion detects that a sheet feeding cassette is mounted, the controller controls a driving portion in such a manner as not to lift a sheet supporting plate for the mounted sheet feeding cassette in the case where it is determined that a sheet feeding cassette nearest a feeding roller of the mounted sheet feeding cassette is drawn or detached.
