摘要： A copier includes a developing unit, a toner container, a first movable unit, and a second movable unit. The first movable unit carries the developing unit and is movable between a close position where a developing roller of the developing unit is located close to a photosensitive drum and a distant position where the developing roller is located away from the photosensitive drum. The second movable unit carries the toner container and is configured to drag the first movable unit from the close position to the distant position. The copier is configured so that while the second movable unit is located at a standby position for the drag, a clearance is formed between the first and second movable units to avoid physical contact between the first and second movable units.

摘要： A sheet stacking device includes sheet stacking portion, electric motor, current detecting portion, abnormality determining portion, and updating portion. The sheet stacking portion is supported to be movable in up-down direction and configured to stack sheets thereon. The electric motor outputs, to the sheet stacking portion, a driving force for moving the sheet stacking portion in up-down direction. The current detecting portion detects a current value of the electric motor. The abnormality determining portion determines that the sheet stacking portion is in abnormal state when the detected current value is greater than a predetermined threshold. The updating portion updates the threshold based on the current value that was detected by the current detecting portion while the sheet stacking portion with a predetermined set amount of sheets stacked thereon was being moved by the driving force received from the electric motor.

摘要： A unit retraction device has a hook member which engages with an engaged portion provided on a unit, and a retraction force generating mechanism which exerts a retraction force on the unit. The retraction force generating mechanism includes a first rotary member which is rotatably disposed on a first rotation pivot and to a rotating end part of which the hook member is coupled, a biasing member of which one end is hooked to the first rotary member and which biases the first rotary member in such a direction that the hook member retracts the unit into the apparatus body, and a second rotary member to which another end of the biasing member is hooked and which is rotatably disposed on a second rotation pivot. The second rotary member rotates in the same direction as the first rotary member as the latter is rotated by the biasing member.
