Abstract
A copying machine equipped with a recording apparatus having multi-nozzle heads for respective color components, cyan, magenta, yellow and black, is disclosed. The copying machine has a device which, if a non-ejecting nozzle is present in the head for black ink among the multi-nozzle heads, stores the number of the non-ejecting nozzle; and a recording control device which, when an ejection signal is given to the non-ejecting nozzle, causes a nozzle of each of the ink heads for cyan, magenta and yellow, the nozzle having the same number as the number of the non-ejecting nozzle, to eject ink.
