Abstract: A device that replenishes developer to a developer unit and includes a storage for storing developer, an agitation member, and a vibration plate. The agitation member has a blade shape and is rotationally driven to agitate the developer in the storage. The vibration plate extends from a top portion towards a bottom portion of the storage along a rotation direction of the agitation member, and includes a vibration portion that vibrates due to contact with the agitation member undergoing rotation. A top end of the vibration plate is fixed and a bottom end of the vibration plate is a free end, and there is a gap between the vibration portion and an inner wall of the storage. The vibration plate is provided with an engagement protrusion towards the free end that engages with the agitation member and causes the agitation member undergoing rotation to deform then spring back.

Abstract: A document feeder includes: a first conveyer that picks up sheets from a sheet bundle sheet by sheet, where rear edge of a preceding sheet overlaps front edge of a succeeding sheet; a second conveyer that conveys each sheet picked up by the first conveyer; a front edge sensor that is disposed on a conveyance path from the first conveyer to the second conveyer, and senses whether the sheet falls within a sensing range; and a shift unit that shifts, while the first and second conveyers convey the sheet, positional relation between the sheet and the front edge sensor by increasing distance therebetween in a direction crossing a sheet conveyance direction, such that the sheet falls outside the sensing range. When the preceding sheet falls outside the sensing range, the first conveyer picks up the succeeding sheet such that the front edge of the succeeding sheet enters the sensing range.
