ABSTRACT:
A copy paper separating method for use in an electrophotographic copying apparatus which forms a latent electrostatic image on a recording member is provided. The method includes the step of depositing fine particles having insulating properties and charged to a polarity opposite of that of the toner image on the surface of the recording member before the copy paper is placed over the recording member, to cause the particles to reduce the electrostatic attraction between the copy paper and the recording member, thereby facilitating separation of the copy paper from said recording member.
