Claims

[Claims for Utility Model Registration] A developing device is provided so as to be able to swing around a support shaft at a position facing the latent image carrier, and development is performed with the developing roller of the developing device in contact with the latent image carrier. In an electrostatic recording device, when the developing roller is in contact with the latent image carrier, the plane containing the rotating shaft of the developing roller and the supporting shaft of the developing device is the tangential plane between the latent image carrier and the developing roller. An electrostatic recording device characterized in that it is configured to be substantially parallel to the .
