Abstract

PURPOSE: To perform development and transcription fixation with a magentic toner by forming an electrostatic latent image on a base through meshes, by forming a master by developing and fixing the image with the magnetic toner, and then magnetizing the toner image on the master by applying a DC magnetic field.
CONSTITUTION: On base 1 of a photoconductive semiconductor, a pictue is projected through meshes to form an electrostatic latent image, which developed and fixed with magnetic toner A.4 to make master 5. Base 1 is a sheet of paper of zinc oxide and magnetic toner A.4 is iron particles or nickel particles, providing the picture solid part with more than 2,000e Hc and more than 500 gauss Br magnetic characteristics, or γ-Fe2O3, Fe3O3 or the like. Picture 4 on master 5 is magnetized by being applied with a DC magnetic field by unit 6. This magnetized toner is applied with magnetic toner 7 and the picture is transcribed on transcription paper 8 and then fixed. The above-mentioned operation is repeated to duplicates 8 from master 5.
