Abstract
The present invention is an electrostatographic toner that includes an organometallic complex of dimethyl sulfoxide with a metal salt as a charge control agent having the structure; (M+n)x ((CH3)2SO2)y (A−q)z where n, q, x and z are integers between 1 and 6, and y is an integer between 2 and 12, The present invention also includes a developer having a toner, an organometallic complex of dimethyl sulfoxide with a metal salt as a charge control agent having the structure; (M+n)x ((CH3)2SO2)y (A−q)z where n, q, x and z are integers between 1 and 6, and y is an integer between 2 and 12, and a carrier particle.
Claims16
