Abstract

The invention provides an image forming apparatus. The image forming apparatus includes a groove, an exposure device and an adjustment member. In the groove, each of end portions of a rotation shaft of a photosensitive drum is inserted. The exposure device is configured to emit a laser light on the photosensitive drum to form an electrostatic latent image. An adjustment member is configured to shift each of the end portions of the rotation shaft to adjust a skew of the laser light.

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, a photosensitive drum is exposed to laser light output from an optical element of an exposure device, thereby forming an electrostatic latent image on the photosensitive drum. At this time, if the exposure device and the photosensitive drum are slightly misaligned, the image on the photosensitive drum will be skewed (skewed), and color deviation will occur. In general, since many components are interposed between the optical element and the photosensitive drum, it is difficult to position them with high precision. [0003] There has been disclosed an image forming apparatus having an exposure device arranged so as to be inclined with respect to the rotational axis of a photosensitive drum, the image forming apparatus finely adjusting the peri...
