Production of composite picture

Abstract

Abstract PURPOSE:To produce freely a monochromatic composite picture of the 1st and 2nd pictures or a double color synthetic picture, by switching the negative and positive of the 1st light image as well as the polarities of a modulating corona by means of a polarity inverting circuit, etc. CONSTITUTION:The drum-shaped and NP type electrophotographic sensitive matters 1 and 2 functioning as latent image carriers are attached to shafts 3 and 4 respectively. The matters 1 and 2 function as a mesh screen and a drum of consecutive faces respectively. The first picture A of a circular image and the 2nd picture B of a triangular image are synthesized into the same recording medium. The latent image of the picture A is formed to the matter 1; while the latent image of the picture B is formed to the matter 2. Furthermore the secondary latent image of the picture A of the matter 1 is formed as a negative image in addition to a positive image of the picture B formed on the surface of the matter 2. These latent images are developed successively with a positive red toner 16 and a negative black toner 17 to produce a double color picture. This color picture is copied on a transcribing material P.
