Claims

[Claims for Utility Model Registration] (1) A device main body includes a latent image carrier, a means for forming a latent image on the latent image carrier, a developing device for developing the latent image with toner, and a toner image. In an electrostatic recording device that is equipped with a means for transferring a toner image onto a recording paper and a means for fixing a toner image on the recording paper, the main body of the device is divided into at least two parts, an upper unit and a lower unit, and the upper unit is connected by a pivot. The developing unit is swingably supported on the lower unit, and the developing unit is mounted on the lower unit so as to rotate in a direction away from the latent image carrier under its own weight, and the upper unit is in contact with the lower unit. In the state
An electrostatic recording device characterized in that a spring is interposed between the developing device and the upper unit to press and fix the developing device in a predetermined position. (2) The electrostatic recording device according to claim 1, which is a utility model, and further comprises a fixing means capable of fixing the developing device at a position different from the predetermined position pressed and fixed by the spring.
