Abstract

An image formation apparatus including a photoreceptor, a charger having a charger member for charging the photoreceptor, a latent image write unit for writing an electrostatic latent image onto the photoreceptor charged by the charger, and a developing device having a developer support with a magnetic field production member, for rendering visible the electrostatic latent image written by the latent image write unit with a developer. Further, the charging member of the charger is disposed under effect of a magnetic field produced by the magnetic field production member of the developing device, and the charging member is made of a nonmagnetic material.
