  • Method of using variably sized coating particles in a mono component developing system
    Patent number: 6605402
    Abstract: The present invention is directed to a non-contact, single-component developing system for electrophotographic machines that effectively reduces the impact of adhesion forces on the development process. The developing system of the present invention utilizes a single-component toner that tends to reduce the adhesion forces that hold the toner particles on a toner support member. Preferably, the toner is combined with large and small silica particles having a concentration by weight that results in an optimum surface coverage of toner particles by large and small silica particles that facilitates a reduction in the adhesion forces holding the toner particles on the toner support member.
    Type: Grant
