Electrophotographic printer comprising an exposure energy correcting

In a developer station for an electrophotographic printing or copying machine, there is provided apparatus which serves to effectively prevent toner dust emergence from the lower region of the developer station which could cause undesirable inking of background areas on the charge image carrier passing through the developer station. This apparatus comprises a generally laterally extending guide plate assembly disposed adjacent the open upper end of the developer station and extending between the magnetic drum or developing roller and an adjacent station sidewall. The guide plate is arranged with a lead end facing the discharge point of the inking gap formed between the developing roller and the charge image carrier for dividing developer mix passing from the inking gap and spilling off the upper end of the developing roller into two branch flows, the first of which passes through the gap formed between the lead end of the guide plate and the adjacent developing roller surface and the second of which is conducted from the opposed trail end of the guide plate against the adjacent station sidewall along which it passes back downwardly into the lower region of the station. The guide plate serves as a solid barrier against the emergence of toner dust from the lower region of the station and the two branch flows serve as fluid seals against such upward escape of toner dust.
