To provide a controller unit optimally connectable to engine units with diversified performance and specifications used in the case of forming an image.
A multi-value error diffusion processing section 201 quantizes M pieces (M is an integer of 2 or over) of input image information are quantized into N pieces (N is an integer of 2 or over) of image data and are output. A dot processing section 202 binarizes the quantized N pieces of image data into binary image data with a relatively high resolution and outputs them. An output data selection section 204 selects whether to output the N pieces of image data or output the binary image data to a connected engine unit based on a selection instruction of a print mode adaptive output selection section 203.
