Abstract

PURPOSE: To obtain a high resolution 2-color copied image in a simple unit, by combining 2 kinds of photoreceptors having photosensitivity and charging characteristics to a specified color light different from each other in a mosaic form.
CONSTITUTION: Microrelieved photosensitive material layer S1 is formed by vapor depositing Se-Te alloy 5 on aluminum plate 2 heated to 74°C through screen 4 in the case of red and black 2-color copying. A ZnO-resin sensitized by Rose Bengal and fluorescein is filled in the recess of layer S1 by a blade method or the like to form photosensitive material S2 and photoreceptor 1. Charger 5 makes positive uniform charging to receptor 1, resulting in charging only material S1 chargeable not negatively but positively. Negative secondary charger 6 discharges toward receptor 1, resulting in charging only material S2 uniformly. Black parts of mosaic photosensitive layer 3 are charged to +, and red parts to -, and white ground parts to about 0 by projecting the light image of a red, black and white original, and layer 3 is developed with a negative toner to black and with a positive toner to red and transferred to a recording sheet.
