Abstract
A recording apparatus according to the present invention comprises a recording unit to record images on a recording sheet, and a photosensor which detects the density of the recording surface of a recording sheet. The apparatus records with the recording unit a given pattern on a given position on the recording sheet subsequent to the termination of image recording by the recording unit. A CPU is provided in order to judge the operating state of the recording unit in accordance with the result of the detection by the photosensor as to the pattern density, thus making it possible to automatically and accurately judge whether the image data are normally recorded. In particular, the CPU, using the output of the photosensor, determines whether the given pattern was recorded satisfactorily. If so, it is assumed that the image data was also recorded satisfactorily.
