Claims

[Claims for Utility Model Registration] (1) An electrostatic latent image is formed by uniformly charging a photoreceptor and selectively discharging the charged charge, and the formed electrostatic latent image is developed to produce toner. In an unnecessary partial static elimination lamp used in an image forming apparatus that forms an image,
A main body consisting of a light emitting element array arranged in the axial direction so as to face the photoreceptor, a condensing optical system that directs diverging light emitted from the light emitting element array to the photoreceptor in a substantially band shape, and a condensing optical system. An image forming apparatus comprising a light shielding member disposed between the system and the photoreceptor and having a slit parallel to the axial direction, and the light shielding member is attached to the main body so as to be movable and detachable in the axial direction. Unnecessary static electricity removal lamp. (2) An unnecessary part of the image forming apparatus according to claim 1, characterized in that the surface of the light shielding member facing the photoconductor and sandwiching the slit is formed of a tapered surface that tapers toward the photoconductor with the slit as the apex. Partial static elimination lamp. (3) A cleaning member whose tip touches the condensing optical system is attached to the axial end of the light shielding member, and the cleaning member rubs the condensing optical system when the light shielding member is moved in the axial direction with respect to the main body. 3. An unnecessary partial static elimination lamp for an image forming apparatus according to claim 1 or 2.
