Abstract
An improved diazo film processing and developing system has warm-up and steady state heaters along with gravity loading of the film drive rollers and cast aluminum pre-heat and developing chambers. The chambers use resilient or leaf spring seals and a stainless steel aqueous ammonia separation chamber is contiguous and directly connected with the developing chamber for maintaining a temperature differential between the two chambers.
