摘要： An electrophotographic apparatus includes a photoconductor drum, also known as an electrostatic latent image holding member, with a magnet placed therein. An electrostatic latent image is formed on the magnetic drum. Then, the drum is brought into contact with a magnetic developer, or toner, in a developer reservoir to have the magnetic developer attached to the photoconductor drum surface by a magnetic force. A removing roller, having an AC voltage applied thereto, is passed in close vicinity of the magnetic drum with the resultant development of images because toner remains at image areas only. In the electrophotographic apparatus, the photoconductor drum, the removing roller or both include two magnetic poles. A device for increasing friction force of the surface of the photoconductor drum, of the removing roller or both may also be provided.

Control electrodes 16 are provided to move charged particles detached from a development roller 2 and to control the movement amount of the charged particles by generating a transfer electric field directly or indirectly between the development roller 2 and a rear electrode 8. A bias electrostatic field is generated between the development roller 2 and the control electrodes 16 by applying a voltage under a jumping start voltage, which is a voltage having the polarity opposite to the polarity of the charged particles and is lower than the jumping start voltage for detaching the charged particles from the development roller 2.
