Fluorinated polymer coated carrier particles |
摘要 |
A carrier bead is disclosed having a core and at least an outer coating of polytetrafluoroethylene or fluorinated ethylene propylene. Use of these fluoropolymers as carrier coatings results in extremely long carrier life and overcomes problems that have heretofore plagued the commercialization of a magnetic brush development system for a plain paper electrostatic copying apparatus.
