ABSTRACT:
Undesired stain is minimized for pearlescent toners, adapted for toning elements having non-tacky and tacky areas that define an image, by including in the toner inert, substantially spherical particles having a particle size of approximately 0.3 to 42 microns and by including a slip-agent surface coating on at least the pearlescent pigment particles, and preferably also on the inert, substantially spherical particles.
