に記載の画像形成装置の除電用光源。[Claims for Utility Model Registration] (1) An image forming device that forms an electrostatic latent image on a photoreceptor, visualizes the electrostatic latent image using a developer, and transfers and fixes the visible image onto copy paper. A lighting circuit and a preheating circuit are connected in parallel to a static elimination light source that eliminates static electricity from the photoreceptor, and a delay circuit that operates with a certain time delay from the activation of the preheating circuit is connected to the lighting circuit. A light source for static elimination for an image forming apparatus, characterized by: (2) The static elimination light source is a pre-transfer static elimination lamp, and the delay time caused by the delay circuit is at most the time from when the print switch is pressed until the effective image area of the first copy on the photoreceptor reaches the cleaning area. Claim 1 characterized in that it is set to time.
A light source for static elimination of an image forming apparatus according to .
