Abstract

The use of small, substantially smearless polymeric particles with abrasive material particles as additives in a dry devel-oper composition which also contains toner and carrier may be enhanced by selective mixing. Such adrnixtures are employed as developers for developing electrostatic latent images.

The use of small, substantially smearless polymeric particles
with abrasive material particles as additives in a dry devel-
oper composition which also contains toner and carrier may be
enhanced by selective mixing. Such adrnixtures are employed
as developers for developing electrostatic latent images.

Small, submicron sized polymeric additives are mixed by ball
milling or other appropriate techniques with the small abra-
sive particles until the abrasive particles coat the poly-
meric additive particles. Toner and carrier where appro-
priate are then introduced and blended to form the developer
mixture.

Selective order of mixing makes possible reduction in carrier
impaction which adversely affects developer life. Other
benefits include better distribution of materials.
