ABSTRACT:
An ink-jet recording apparatus is provided which promptly resumes image recording in the case of non-ejection of ink from an ejection nozzle(s) of a recording head. The ink-jet recording apparatus includes sub-tanks and a recording head with a plurality of ejection nozzle groups composed of ejection nozzles. The recording head selectively ejects ink inside the sub-tanks to perform image recording. The ink-jet recording apparatus further includes an image recording control device that selects at least one of the plurality of ejection nozzle groups for image recording, and a non-ejection status detection device that detects whether there is any ejection nozzle in a non-ejection state. When the non-ejection status detection device detects one or more ejection nozzles in a non-ejection state, the image recording control device selects one out of the plurality of ejection nozzle groups that is without any of the ejection nozzle(s) in a non-ejection state for image recording.
