ABSTRACT:
An image recorder includes a cleaning unit having an opening which faces a photoconductive drum in a predetermined set position of the unit, and other process units which are arranged around the drum together with the cleaning unit. A process kit which at least includes the cleaning unit is removable from the image recorder independently of the drum. The image recorder is constituted by an upper and a lower unit, the upper unit being openable away from the lower unit. A member is provided which opens and closes the opening of the cleaning unit in an interlocked relation with the upper unit. The drum and process kit may be opened and closed together with the upper unit or, alternatively, the process unit may be opened and closed together with the upper unit with the drum retained by the lower unit, as desired.
