Abstract

PURPOSE: To print a letter and a format in different colors by a printer, wherein a memory for printing information and a memory for format information are separately provided, by sending video signals to a multiplex modulator to form latent images separately on the surface of a photosensitive drum.
CONSTITUTION: Letter patterns and format patterns are memorized beforehand in a letter generating means 22 and a format generating means 24, respectively. In accordance with an instruction from MT21, a video signal 22' representative of printing information and a video signal 24' representative of format information are simultaneously sent to a multiplex modulator 28 through a synchronizing circuit 26. In the multiplex modulator 28 which has received video signals 26', 26", a laser beam 27' is modulated to form separately latent images in accordance with the printing information and format information on the surface of a photosensitive drum 35. The latent images in accordance with the mentioned information are developed and synthesized in two kinds of developing units 37, 38 having different biases. Thus, two different colors are simultaneously transferred to paper 42.
