ABSTRACT:
Between an image forming unit and an automatic developing unit disposed adjacent to the unit, an intermediate chamber having an exhaust device is provided for transferring a photosensitive material from the image forming unit to the developing unit. Even when the vapors of chemical solutions accommodated in the developing unit for development treatment flow into the intermediate chamber through a clearance created in an outlet opening for delivering the material into the developing unit therethrough, the vapors are prevented from flowing into the image forming unit by being temporarily retained in the chamber and released to an exhaust channel. While the exhaust device promotes the flow of chemical vapors from the developing unit into the intermediate chamber by discharging air from the chamber, the device causes air to flow from the image forming unit into the chamber through a clearance produced in an inlet opening for receiving the material into the chamber therethrough, thereby preventing the vapors from flowing out of the chamber into the image forming unit.
