A selective charge removal system for a copier uses a transparent electrochromic display with many segments or dots thereon and a back-lighting unit such that only a specified area which is precisely defined on the photosensitive body of the copier is exposed to the light from the back-lighting unit. These segments or dots are driven to an intermediate color state during a wait period before a copying operation of the copier is started such that the color conditions of the electrochromic display can be changed quickly.
