A non-ejecting nozzle detecting method comprises: setting a specified processing liquid deposited pattern; ejecting the processing liquid from processing liquid nozzles onto a recording medium to form the processing liquid deposited pattern; ejecting colored ink from ink nozzles corresponding to the processing liquid nozzles selected as non-ejection detection targets onto the processing liquid deposited pattern, and recording linear colored ink images on the recording medium to thereby form a processing liquid non-ejection detection pattern; detecting, based on changes in densities and line widths of the linear colored ink images, a non-ejecting processing liquid nozzle from the processing liquid nozzles selected as the non-ejection detection targets. |
