Abstract
Image quality of an image generated by a xerographic or equivalent image generating process may develop non-uniform charge characteristics, in addition to other negative effects, as a result of positive over-spray, but these negative effects can be at least attenuated by exposure of the photoreceptor to fluorescent light.
Claims36
A method for forming an image, comprising:
- charging a photoreceptor at least once;
- exposing the charged photoreceptor to an input image to form a latent image;
- developing the latent image on the photoreceptor at least once;
- transferring the image from the photoreceptor to a support;
- exposing areas of the photoreceptor subject to positive over-spray to fluorescent light at least once;
- cleaning the photoreceptor at least once;
- and
- erasing the photoreceptor at least once.
