Title: Ink jet recording apparatus and a method for discharge recovery thereof

Abstract: An ink jet recording apparatus is to record by discharging ink and colorless record processing liquid to a recording medium from ink discharge ports and record processing liquid discharge ports. A detector detects discharge or non-discharge from every discharge port. The discharge recovery process for the processing liquid discharge ports is executed by discharging record processing liquid out of non-discharged ports to the recording medium. With the discharge recovery process thus arranged to be executable on the surface of a recording medium, not only the slowdown of printing speed is prevented, but also, the apparatus main body can be made smaller because there is no need for any provision of receptacle for receiving exhausted processing liquid.
