Device for the development of an electrostatic charge image with the aid of magnetic brushes.

摘要

Device for the development of an electrostatic charge image with the aid of magnetic brushes comprising:
a trough-shaped reservoir (1) of which two long opposite sloping walls (2, 3) lie in planes which are intersecting at the bottom (4) of the reservoir,
two magnetic brush developing rollers (5, 6) which rotate on their axes in directions away from each other at the side which is directed toward the charge image,
a magnetic brush roller (18) for transporting the developing powder toward the developing rollers and
mixing means consisting of groups of parallelly-erected partitions (23, 24) which have been fixed opposite to each other to the sloping walls of the reservoir.
