PROBLEM TO BE SOLVED: To detect even a discharge failure at a part of a nozzle array of a recording head in a detection operation for a quantity of ink remaining. SOLUTION: In the facsimile apparatus having a recording part which records by discharging ink to a recording medium from a recording head 5 equipped with a nozzle array 5c of a plurality of ink discharge nozzles, a photosensor is set with a lightemitting element 81 and a light-detecting element 82 disposed so that an optical axis is a predetermined angle to the nozzle array of the recording head 5. An ink discharge detection signal is generated at a change of an output of the photosensor when the discharged ink from the recording head traverses the optical axis. The presence/absence of an ink discharge, that is, whether the ink is discharged is inspected accordingly. The ink is discharged at a time point when the recording head 5 is located at each of discharge positions (1)-(n), and the ink discharge is detected by the photosensor. The ink discharge at each part of the nozzle array is inspected in this manner. |
