Electrostatic recording apparatus having a floating electrode on a photoelectric transfer member

摘要

An electrostatic recording apparatus 1 for forming an electrostatic image on an electric charge carrying member 2 comprises a photoelectric transfer member 14 spaced from the electric charge carrying member 2, a floating electrode 16 provided on a first surface of the photoelectric transfer member 14, an electric power supply 27 for applying a voltage between the second surface of the photoelectric transfer member 14 and the second surface of the electric charge carrying member 2, and an exposure device 8 for exposing a second surface of the photoelectric transfer member 14. The floating electrode 16 having an electric discharge terminal 18a close to the electric charge carrying member 2. When the exposure device 8 exposes a second surface of the photoelectric transfer member 14, the carriers generated in the photoelectric transfer member 14 move toward the floating electrode 16 to cause an electric discharge between the electric discharge terminal 18a of the floating electrode 16 and the electric charge carrying member 2, which allows an electrostatic image to be formed on the electric charge carrying member 2.
