Abstract
A recording apparatus for receiving a page description language representing image data to be recorded and for recording an image includes a memory for storing bit image data smaller than a one-page capacity, a recording unit for recording the bit image data stored in the memory, a unit for generating partial bit image data of an area corresponding to the memory on the basis of the input page description language, and a controller for storing the partial bit image data generated by the generating unit in the memory, and for causing the recording unit to repeat recording of the partial bit image data stored in the memory until one page of bit image data has been recorded.
