Claims

[Scope of utility model registration request]

In a device that transfers toner that is attracted to the surface of a photoconductor onto copy paper under the application of a transfer electric field,
A conductor that applies a ground or bias voltage is placed close to or in contact with the back of the copy paper that is attracted to the surface of the photoreceptor after transfer, and the copy paper is exposed to light by the attraction between this conductor and the electrostatic charge on the copy paper. A transfer separation device for an electrophotographic copying machine configured to be separated from a body surface.
