ABSTRACT:
An improved magnetic brush development apparatus for applying developer material to a latent image on a moving image carrying member wherein mounting of a take-off skive is facilitated. The development apparatus includes a housing having a portion defining a sump adapted to contain a supply of developer material, and a magnetic brush located substantially within the housing in spaced relation to the sump portion for applying developer material to the latent image. A feed mechanism including a metering assembly located within the housing between the sump portion and the magnetic brush transports developer material from the sump to the magnetic brush, and a mechanism located in the sump portion agitates developer material and transports developer material to the feed mechanism. A take-off skive for stripping development material from the magnetic brush after application to a latent image and directing such material to the sump portion is mounted so that the skive is self-adjustably supported between the metering assembly and the magnetic brush.
