Abstract

The invention provides an image forming device. The image forming device has a tank, an exposure device, and an adjustment member. One end portion of the rotation shaft of the photosensitive drum is inserted into the groove. The exposure device forms an electrostatic latent image by irradiating laser light on the photosensitive drum. The adjusting member adjusts the tilt of the laser beam by moving one end of the rotating shaft in a direction other than the vertical direction in the groove. According to the present invention, it is possible to adjust the inclination of laser light with a simple structure.

Description

technical field [0001] The present invention relates to an image forming apparatus having a photosensitive drum that forms 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 (displaced), the image on the photosensitive drum will be tilted (skewed) and 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 is disclosed an image forming apparatus having an exposure device arranged so as to maintain an inclination with respect to a rotation axis of a photosensitive drum, the image forming device finely adjusting th...
