Abstract

PURPOSE:To prevent the unevenness of the density of a picture by feeding a developer over stirring and mixing by a rotary cylinder and spiral blade fixed on its internal wall. CONSTITUTION:Cylinder 32, having a spiral blade fixed internally, is rotated to move a developer inside of the cylinder. The developer is elevated and dropped repeatedly inside of cylinder and then fed to the other end being stirred and mixed sufficiently. This constitution has no dead space and the developer is sufficiently stirred, and consequently the developer is sufficiently stirred and mixed during the operation of the developing device without deteriorating the developer, so that the unevenness of picture density will never appear.
