摘要： A process cartridge includes a protective agent, a photoconductor, a charging unit, a development unit, a cleaning unit, and an application unit. The protective agent includes paraffin as main component. The photoconductor has a surface including polycarbonate applied with the protective agent. The development unit develops a latent image on the photoconductor. The cleaning unit removes materials remaining on the photoconductor. The application unit applies the protective agent to the surface of photoconductor. One peak in a given binding energy range is used to determine a coating condition of the photoconductor coated by the agent. The coating condition is determined by comparing an area ratio A0 before applying the agent and an area ratio A after applying the agent, each of which is an area ratio with respect to a total area of C1s spectrum of the photoconductor. The coating ratio of the photoconductor is computed by (A0−A)/A0×100.

摘要： An image forming apparatus of includes a developing device bifunctioning as a cleaning device for collecting toner grains left on a photoconductive drum after the transfer of a toner image from the drum to a paper sheet or similar image transfer medium. In the event of toner collection, a DC voltage is applied that causes the residual toner to move from the drum toward a developing sleeve. A main-pole magnet generates, at a position where the developing sleeve faces the drum, a magnetic field of between 100 mT and 200 mT in a direction normal to the surface of the sleeve.
