Claims

[Scope of utility model registration request]

(1) A recording section that records an image on a photoreceptor; and an optical system section that emits a light beam that is incident on the rotating polygon mirror from the light beam generating means via the lens to the recording section via the imaging lens. , an image recording device comprising a control unit that controls a recording unit and an optical system unit, wherein an exit hole provided in the optical system unit for emitting a light beam between the optical system unit and the recording unit is provided. The image recording device is characterized in that a transparent body whose surface facing the recording section is treated so as not to be charged is fixedly provided, and the optical system section is substantially sealed from the recording section. .

(2) The image recording apparatus according to claim 1, wherein an antistatic agent is coated on the surface of the transparent body facing the recording section.

(3) The image recording device according to claim 1, wherein the transparent body is made of a conductive film.

(4) The image recording device according to claim 1, wherein the transparent body is made of conductive glass.
