Abstract

In a magnetic brush development system, it is desirable to have elongated magnets disposed interiorly of a non-magnetic tubular member. Frequently, it is desirable to have an insulative tubular member which has the frictional coefficient required to advance the developer material. In order to achieve this, the tubular roll may be made from a roughened conductive material. Thereafter, the conductive material is coated with an insulative material which conforms to the surface roughness thereof. In this way, the insulating roller has a desired coefficient of friction.
