Abstract
A cleaning blade is provided for cleaning residual toner particles and other contaminants from an electrostatic imaging surface comprising a surface having rigid spherical protuberances adapted to be pressed against the imaging surface to form a seal between the blade and imaging surface which retards flow of particles between the blade and imaging surface.
