Image formation apparatus and charger used therewith

An image formation apparatus comprising:

• a photoreceptor;
• a charger having a charging member for charging the photoreceptor, a removal member disposed in contact with the photoreceptor in the upstream of the charging member, for removing a deposit on the photoreceptor, and a partition member for partitioning the charging member and the removal member, and causing a removed substance peeled off from the removal member to collide therewith;
• a latent image write unit for writing an electrostatic latent image onto the photoreceptor charged by the charger;
• a developing device having a developer support including a magnetic field production member, for rendering visible the electrostatic latent image written by the latent image write unit with a developer;
• and
• wherein the partition member is disposed under the effect of a magnetic field produced by the magnetic field production member of the developing device.

An image formation apparatus comprising:

• a photoreceptor;
• a charger having a charging 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 including a magnetic field production member, for rendering visible the electrostatic latent image written by the latent image write unit with a developer,
• wherein the charging member of the charger is coated at least on an outermost peripheral surface with a cylindrical surface layer film formed of a polymeric material;
• and a material of the surface layer film has a Young's modulus of 0.6 GPa or less.
