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 is provided in the opening/closing member and 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： A sheet feeding device includes a sheet storage unit, a stacking unit, a raising unit, a sheet detection unit, an attachment detection unit, and a control unit. The sheet storage unit may be attached to and drawn out of an apparatus main body. The stacking unit is raised by the raising unit and is lowered when the sheet storage unit is drawn out. The attachment detection unit detects attachment of the sheet storage unit to the apparatus main body. The control unit determines whether an amount of sheets stacked on the stacking unit exceeds a predetermined amount based on detection results. If the sheet detection unit continues to detect sheets when the sheet storage unit goes from attached, to not attached, to attached to the apparatus main body, the control unit determines that the amount of sheets stacked on the stacking unit does not exceed the predetermined amount.

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.
