Drum cartridge and image forming apparatus having residual toner conveying pipe

A drum cartridge comprising:

• a photosensitive drum rotatable about a drum axis extending in an axis direction;
• a drum cleaner comprising:
• a cleaning member configured to remove transfer residual toner from a circumferential surface of the photosensitive drum;
• and
• a cleaning housing configured to accommodate transfer residual toner removed from the circumferential surface of the photosensitive drum by the cleaning member;
• a first drum side plate configured to support a first end portion of the photosensitive drum in the axis direction;
• a second drum side plate located distant from the first drum side plate in the axis direction and configured to support a second end portion of the photosensitive drum in the axis direction;
• a pipe located between the first drum side plate and the second drum side plate in the axis direction and extending in the axis direction, a first end portion of the pipe in the axis direction connecting to the first drum side plate, a second end portion of the pipe in the axis direction connecting to the second drum side plate, the pipe having a transfer residual toner discharge hole discharging transfer residual toner;
• a conveyor device configured to convey transfer residual toner from the cleaning housing to the pipe;
• and
• a receiving part configured to receive a toner cartridge such that the toner cartridge is rotatable between a first position and a second position around an axis parallel to the drum axis in a state of supporting the toner cartridge,
• the transfer residual toner discharge hole not facing a transfer residual toner receiving hole of the toner cartridge in a case the toner cartridge is located in the first position, the transfer residual toner discharge hole facing the transfer residual toner receiving hole of the toner cartridge in a case the toner cartridge is located in the second position.
