る原稿濃度検出装置。[Scope of Claim for Utility Model Registration] An exposure unit that includes a light source for document illumination is moved relative to the document during exposure, and the reflected light from the document is passed through an optical system to uniformly charge the document in advance. Obtain an electrostatic latent image by forming an image on a photoreceptor,
In an image forming apparatus, an optical fiber is attached to an exposure unit and transmits document density information, and an optical fiber is attached to an exposure unit in a direction in which light is emitted from the optical fiber and is moved along with the exposure unit. What is claimed is: 1. A document density detection device comprising a plurality of light receiving elements fixedly arranged.
