Abstract: A development apparatus in which a plurality of differently colored particles are dispensed into a common sump. Differently colored particles are dispensed in a pre-selected ratio to form a resultant mixture of particles in the sump having a pre-selected color. This mixture is subsequently deposited on a latent image rendering the image visible in the pre-selected color.
