摘要：
A novel magnetic, electrophotographic, development or toner powder is provided comprising essentially spherical particles with a diameter between 5 and 50.mu.. The particles contain small ferromagnetic particles, highly conducting carbon, at least 5% sublimable dyestuff and at least 4% of a surface active agent. The particles are preferably structured to have an inside nucleus zone containing dyestuff and surfactant and an outside shell zone which contains the magnetic material and the highly conducting carbon.
