Abstract: PROBLEM TO BE SOLVED: To realize resist correction in one picture element in a main scanning direction and to obtain a good-quality image having neither color slurring nor color blotting by distributing image data to the adjacent picture element in accordance with positional deviation in the picture element and performing image exposure. SOLUTION: A control part accesses the image density information of one line in main scanning from the page memory of the image data 202 and stores it in a line memory 301. Picture element density information is shifted one by one to memories 302a to 302c from the line memory 301. A coefficient is accessed from a ROM (3) 205 so as to perform multiplication processing in multipliers (1) 303a to 303c. Furthermore, the addition processing is performed in an adder 304 and the processed result is outputted as the i-th picture element density information newly corrected. The picture element density information is outputted from the line memory 301 in a state that a picture element number is incremented by one, and the picture element density information newly corrected is outputted from the adder 304. Finally, the corrected image density information of one line in main scanning is outputted from a memory for write(1) 305a to an LED array head.
