Claims (1)

[Scope of Claim for Utility Model Registration] 1. After uniformly charging the surface of an endless belt-shaped photoreceptor by a charging means, the document fed and conveyed by the document feeding and conveying means is exposed to light by an exposure optical system and its reflected light is emitted. forming an electrostatic latent image on the photoreceptor by
This electrostatic latent image is visualized by a developing means, the visualized image is transferred by a transfer means onto a transfer paper fed and conveyed by a transfer paper feed conveyance means, and the image transferred to the transfer paper is fixed. In the electrostatic recording apparatus, the surface of the photoreceptor is fixed by a cleaning means and the surface of the photoreceptor after transfer is cleaned by a cleaning means, in which a developing roller in the developing means is brought into contact with the photoreceptor in a state where the photoreceptor is concavely recessed. The photoreceptor is installed in a vertically elongated state with a narrow interval in the center of the belt, and around the photoreceptor there is an electrostatic latent image forming means formed by the charging means, document feeding means, and exposure optical system. and the cleaning means, the developing means, and the cooling means for cooling the inside of the machine.
An electrostatic recording apparatus characterized in that each process unit of the transfer means, the fixing means, and the transfer paper feeding means are arranged in order from the top. 2. A drive motor for driving each process unit is provided, and a gear is provided for transmitting the driving force of the drive motor to the developing means in a substantially directly connected state,
2. The electrostatic recording apparatus according to claim 1, further comprising relay transmission means for transmitting the driving force of said drive motor to each remaining process unit.
