Title:
光走査装置、およびそれを備えた画像形成装置
Document Type and Number:
Japanese Patent JP6965800
Kind Code:
B2
Abstract:
An optical scanning device that scans a photoreceptor with light, the device includes: a light emitter that emits light according to a supply current amount; a source-side optical system that includes an optical element corresponding to the light emitter, the optical element transmitting and shaping the light emitted from the corresponding light emitter; a polygon mirror that cyclically deflects the light shaped by the source-side optical system; an image-side optical system that condenses the light deflected by the polygon mirror on a surface of the photoreceptor; a motor that rotates the polygon mirror; and a light source controller that: monitors a temperature of the optical element; and adjusts the supply current amount for the light emitter or adjusts the temperature of the optical element corresponding to the light emitter to make a temperature difference between the light emitter and the corresponding optical element fall within an allowable range.
