Summary: | The development apparatus of an electrostatographic printer has a donor roll (74) formed by mixing resin particles with conductive particles and subsequently extruding or centrifugally casting the mixture into a cylindrical shell. The shell is cut to the desired length and journals are attached to each end of the shell. The resin particles are thermoset particles preferably phenolic resin particles, and the conductive particles are preferably graphite particles. |
