Abstract

PURPOSE: To obtain a recording device capable of recording in two colors by using two kinds of toner, by setting the light emission quantity in a luminescent spot in a cathode-ray tube in two steps, and corresponding the image information for two- color recording to each light emission quantity.
CONSTITUTION: When an image signal synthesized with information A and information B is applied to a CRT3, the information A and information B are transformed to one-dimensional image through the luminescent spot of high light emission quantity and light emission quantity of 0, respectively. A developer DB used in a developing device 5 contains negatively charged black toner so as to make information B visible. A developing device 6 is provided to make visible the electrostatic latent image part corresponding to information A, and the developer DA used therein contains positively charged red toner. Thus, since information A and information B are transoformed to red and black images on recording sheet S, respectively, a recording device capable of recording in two colors may be obtained.
