Electrophotographic copier

Claim 1

A electrophotographic copier for implementing an electrophotographic copying process, comprising in combination: a photoconductor; a charging means for uniformly charging said photoconductor and for transferring an image to be developed on said photoconductor to a copy paper; an exposing means for exposing said charged photoconductor to an optical image at an exposure site of an exposure station to form a latent electrostatic image thereon, said exposing means being juxtapositioned to said charging means at a distance such that dark decay of said photoconductor before exposure is substantially eliminated; a developing means which develops said latent image with toner particles; an illuminating means positioned after said exposure means; a fixing means which fixes said transferred toner particles in an imagewise manner to said copy paper; a cleaning means which cleans said photoconductor, a feeding means which carries said copy paper to said charging means during the image transfer phase of said copying process; and a means for controlling the feeding means to transport a copy paper to the charging means synchronously with the movement of said photoconductor so as not to interfere with exposing of a complete optical image to said photoconductor by said exposing means said photoconductor, charging means, exposing means and fixing means being adjusted to said feeding means such that copy paper with the transferred image thereon passes said exposure station after completion of exposure of said optical image; said copy paper following a path so as to be transported over said exposure site to said fixing means.
