Abstract

In a color electrophotographic printing machine, frequently the developer material comprises carrier granules and a mixture of two differently colored toner particles forming a resultant third color. Thus, the mix of the two toner par-ticles results in the desired third color. After extended usage, it has been found that the mixture of the two toner particles separates out into their individual colors. In order to obviate this problem, the toner particles may be periodically removed from the developer housing and replaced with a fresh charge thereof. Thus, the carrier granules of the original developer mix may be continually reused with different new charges of toner particles.
