Claim 1

In a selective charge removal system for a copier, said copier comprising a photosensitive body, charging means for charging said photosensitive body, developing means for developing an image on said photosensitive body, light-emitting means disposed between said charging means and said developing means for selectively removing charge either from an electrostatic latent image formed on said photosensitive body or from a specified area on said photosensitive body for forming an electrostatic latent image thereon, and control means for controlling the operation of said light-emitting means, the improvement wherein said light-emitting means comprise a transparent electrochromic display having a plurality of segments or dots arranged thereon, and a back-lighting unit, said control means including driving means for driving each of said segments or dots into an intermediate color condition during a wait period prior to a copying operation of said copier, said intermediate color condition being a state between the colored and colorless states of said segments or dots, whereby the display conditions of said electrochromic display can be changed more quickly.
