Image forming apparatus and method for forming image

摘要

Data concerning a transfer pattern of a lamination transparent film is not externally sent and stored in a memory but is generated by a random pattern generating module of a color controlling DSP. A random number generating section generates a pseudorandom number for each dot of one line; a tone data obtaining section obtains tone data corresponding to the pseudorandom number; and a transferring section transfers the tone data to a head signal converting ASIC. Tone data for each dot of one line is alternately written in line buffers. Using the tone data written in the line buffers, a thermal head transfers transparent film.
