Abstract

PURPOSE: To recover and regenerate photoreceptor residual toners in a multicolor copying machine by means of exclusive cleaning members in each color independently.
CONSTITUTION: In configuration of two-color copying machine, 4 is the black toner exclusive developing unit, 5 is the red toner exclusive developing unit, and further 9 is the first cleaning means. In this copying machine, a black toner exclusive cleaner 8 which is a second cleaning means is provided. The cleaning member 8a is, while delopment with block toner undergoes, designed to abut against or approach the surface of photoreceptor 1, and while development with red toner undergoes, is designed to oscillate in the direction of arrow C around a fulcrum 8c, thereby retreating from the surface of the photoreceptor 1. While development with black toner undergoes, the second cleaning means operates, and the residual toner is captued, and is led to a discharge port 8d. by providing the second cleaning means by prlurality, by the number of colors used, each color may be recovered and regenerated.
