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.

Image formation apparatus and charger used therewith

Charger and image formation apparatus using the charger

A transfer device for transferring an image on an image carrier to a recording material the transfer device includes a transferring member adapted to nip and convey the recording material between the transferring member and the image carrier a guard resin layer having a surface microhardness not smaller than surface microhardness corresponding to polyimide, the guard resin layer provided on a surface of the transferring member and an adjustment resistance layer provided as a ground layer of the guard resin layer the adjustment resistance layer adapted to inhibit an accumulation of charge in the guard resin layer Or, the guard resin layer made of an epoxy resin is provided on the surface of the transferring member the adjustment resistance layer having a smooth interface with the guard resin layer the adjustment resistance layer adapted to inhibit accumulation of charge in the guard resin layer. Furthermore, a scraper for cleaning is provided on the surface of the transferring member so as to contact with the surface of the transferring member. An image-forming apparatus is constructed by using the transferring device.
