Claims

[Scope of utility model registration request]

a photoconductor having a photoconductive layer on a transparent and conductive support; a first charging means for first charging the photoconductor to a predetermined polarity; a first exposure means for forming a first electrostatic latent image; a first developing means for regularly developing the first electrostatic latent image to form a first developed image; and light for removing static from the support side of the photoreceptor. a static eliminating means, a second charging means that performs a second charge of the same polarity as the first charge, and a second exposure means that performs negative exposure corresponding to the second image information to form a second electrostatic latent image; A two-color image forming apparatus comprising: a second developing means for reversing and developing the second electrostatic latent image to form a second developed image.
