Abstract
The invention involves a method for making one component or single component toner compositions for developing electrophotographic images. A binding component is mixed with magnetic particles, pulverized, then carbon black is mixed with the powder and fixed to the surface of the particles. Compositions having a measured resistivity of 4.3.times.10.sup.3 to 4.3.times.10.sup.6 ohm-cm at a D.C. field of below 20 volts/cm under substantially no-load conditions are selected for use.
