Color image forming apparatus having scanning lens disposed in reverse orientation

摘要

A color image forming apparatus forms color images on a recording medium by superposing images one after another. The color image forming apparatus includes at least one image bearing member and a plurality of scanning units. At least the one image bearing member bears a latent image thereon. The plurality of scanning units includes a first scanning unit and a second scanning unit. Each scanning unit scans a light beam over at least the one image bearing member to form the latent image thereon. The first scanning unit and the second scanning unit share at least one lens having an optical axis and a shape substantially symmetrical with respect to the optical axis. At least the one lens is disposed in a reverse orientation rotated 180 degrees from a normal orientation about the optical axis.
