Abstract

PURPOSE:To reproduce fine half tones by means of simple constitution and prevent dirt of the white portion by providing periodical amplitude modulation to video signals except the white portion at least. CONSTITUTION:After photosensitive material 21 is set on the drum, driven to rotate and charged uniformally by charging equipment 22 to be about 1000 V, an electrostatic latent image is formed by exposure from CRT 16. The latent image is developed 23, transcribed 25 and fixed by the fixer. In this case, brightness modulation of CRT 16 is applyed by providing the output signal of output amplifier to the glit and beams are controlled by providing the output of power source 17 to the glit. As the result, fine half tones and strips of contact prints can be reproduced by the simple constitution and generation of dirt of the white portion can be prevented by providing periodical amplitude modulation to the video signals except the white portion at least.
