Abstract
An image forming apparatus includes a compressed air generator, a nozzle, a tube, a cooling device, and a drain discharging portion. The compressed air generator generates and injects compressed air onto at least one of a recording medium and components in the image forming apparatus. The compressed air is injected from the nozzle. The tube connects the compressed air generator and the nozzle, and the compressed air passes through the tube. The cooling device cools at least a portion of the tube. The drain discharging portion discharges drain fluid generated in the tube during cooling by the cooling device.
Claims14
An image forming apparatus, comprising:
- a compressed air generator to generate and inject compressed air onto at least one of a recording medium and components in the image forming apparatus;
- a nozzle from which the compressed air is injected;
- a tube to connect the compressed air generator and the nozzle, through which the compressed air passes;
- a cooling device to cool at least a portion of the tube;
- and
- a drain discharging portion to discharge drain fluid generated in the tube during cooling by the cooling device in response to the recording medium completing a conveyance in the image forming apparatus.
