Abstract

The invention provides an image forming device. The image forming apparatus has a photosensitive drum, an exposure device, a holding member, and a main adjustment member. The photosensitive drums are provided for each of a plurality of colors forming a color image. The exposure device forms an electrostatic latent image by irradiating laser light to each of the photosensitive drums. The holding member supports one ends of the rotation shafts of all the photosensitive drums. The main adjusting member adjusts the tilt of the laser light by moving the holding member in a vertical plane. Accordingly, it is possible to adjust the tilt of the laser beam with a simple configuration.

Description

technical field [0001] The present invention relates to an image forming apparatus having a photosensitive drum for forming an electrostatic latent image. Background technique [0002] In an electrophotographic image forming apparatus, an electrostatic latent image is formed on a photosensitive drum by exposing a photosensitive drum with laser light output from an optical element of an exposure device. At this time, if the exposure device and the photosensitive drum are slightly displaced, the image on the photosensitive drum will be tilted (skewed) and a color shift will occur. Generally, since a plurality of components are interposed between the optical element and the photosensitive drum, it is difficult to position both with high accuracy. [0003] There has been disclosed an image forming apparatus having an exposure device arranged so as to maintain an inclination with respect to a rotational axis of a photoreceptor drum, which finely adjusts the peripheral speed of t...
