Pressure fixing a single component toner with polyamide-rosin

摘要

A pressure fixable single component electrophotographic toner or developer composition of a particle size of from 10-40 microns comprising a specialized low melt viscosity polyamide resin composition and a magnetic oxide component. Highly conductive carbon may be added to control the resistivity of the developer particles. The developer comprises from 65-50 percent of the magnetic oxide component and from 35-50 percent of the polyamide resinous component.
