Abstract

Disclosed are colored magnetic toner compositions comprised of non-magnetic toner components having incorporated therein a magnetic powder, such as mag-netite. More specifically, the colored magnetic toner composition can contain a styrene n-butylmethacrylate copolymer containing a cyan pigment, a magenta pigment, and a yellow pigment, which composition has incorporated therein a magnetite, such as particles of iron oxide. Generally, the iron oxide particles are present in the amount of from about 30 percent to about 70 percent by weight. Additionally, there can be further incorporated into the color developer com-position iron powder, about 10 to 30 percent by weight.
