Abstract
A method of cleaning a discharge port surface of an ink jet recording apparatus includes wiping the surface using a blade having a certain contact area with the surface and rubbing the surface using a rubbing member having a larger contact area with the surface than the blade. The wiping and rubbing operations are performed independently of each other so that their different purposes can be better accomplished. For example, since rubbing the surface need not be done as often as wiping, they can both be performed at optimum intervals. The rubbing member can be removably mounted to a replacement ink cartridge so that the rubbing member can be conveniently replaced at the same time as the cartridge.
