ABSTRACT:
A method is described for the development of a surface having imagewise tacky and nontacky areas comprising arranging toner particles in the form of an elongated mound on a section of said surface and then distributing said toner particles over said surface by pushing the elongated mound across the surface with at least one pad with at least a portion of the mound beneath the leading edge of the pad, whereby the distributed toner particles become imagewise adhered to said surface.
A toner applicator comprising a housing for containment of toner, at least one free-moving weight within said housing for breaking up toner aggregates and agitating the toner, means to release toner from the housing, and at least two hinged pads mounted on the housing, is particularly adapted to carry out the method of development.
