Abstract
Abstract An image recording apparatus having a stand-by mode in which recording operation is interrupted during recording for stand-by. The apparatus includes a recording head for recording on a recording medium, a head temperature detecting device for detecting the temperature of the recording head, a memory device for storing temperature information detected by the head temperature detecting device when recording in the stand-by mode is interrupted, a stand-by time counting device for counting an interruption time for recording operation in the stand-by mode, and a head driving controlling device for transmitting a driving signal, to the recording head, adapted to a temperature stored in the temperature memory device and in interruption time calculated by the stand-by time counting device on resuming after recording operation is interrupted in the stand-by mode.
