IMAGE FORMING APPARATUS AND METHOD FOR FORMING IMAGE

摘要

PROBLEM TO BE SOLVED: To eliminate the need to provide a dedicated memory for storing pattern data for transparent film lamination.

SOLUTION: Data concerning a transfer pattern of lamination transparent film are not externally sent and stored in a memory but generated by a random pattern generating module 23 of a color controlling DSP 22. A random number generating section 23a generates a pseudorandom number for each dot of a line; a tone data acquiring section 23b obtains tone data corresponding to the pseudorandom number; and a transferring section 23c transfers the tone data to a head signal converting ASIC 24. Tone data for each dot of a line is alternately written in line buffers 1 and 2. Using the tone data written in the line buffers 1 and 2, a thermal head 130 transfers transparent film 120F.
