Abstract: An image forming apparatus includes an attachment part and a sheet feeding cassette attached to the attachment part. The sheet feeding cassette includes a cassette main body, a lift plate, a lock member and a biasing member. The lift plate is supported in a turnable manner. The lock member is movable between a lock position where a turning of the lift plate is restricted and a release position where the turning of the lift plate is permitted. The biasing member biases the lock member to the lock position. In a state where the sheet feeding cassette is not attached to the attachment part, the lock member is biased by the biasing member to be positioned at the lock position. In a state where the sheet feeding cassette is attached to the attachment part, the lock member is movable either to the lock position or the release position by hand.

Abstract: A sheet conveyance device includes a sheet passage, a first sheet stacker, a second sheet stacker, and a sheet feeder. The first sheet stacker has a bottom and a lift. The sheet feeder includes an opening and a feed roller. The sheet conveyance device includes an assist plate supported to be movable between a first and a second position and an urging member. With the first sheet stacker mounted in an apparatus body, the assist plate moves from the first to the second position against the urging force of the urging member to allow passage of a sheet from the first sheet stacker to the sheet feeder. With the first sheet stacker removed from the apparatus body, the assist plate is urged by the urging member to move from the second to the first position to support the sheet conveyed from the second sheet stacker to the sheet feeder.
