Abstract
A developer mixer for an electrophotographic copying machine comprises a shaft which is rotatably mounted in a developer tank and a plurality of fins affixed obliquely to the shaft. Each fin has a fan-shaped grooved section and the missing sections of mutually adjacent fins are at opposite directions with respect to the shaft. Each fin has a plurality of notches along the periphery such that the liquid being mixed can pass therethrough when the shaft is rotated and hence that the unfavorable effects of centrifugal force can be reduced.
