Abstract
Toner compositions that having spherical particles and provide stable density. The toner compositions also comprise and deliver a silicone oil to the cleaning subsystem in the image forming apparatus by incorporating an inorganic fine powder additive package that has been mixed with silicone oil in a manner such that the toner is blended with the inorganic fine powder and silicone oil.
Claims20
A process for producing a toner composition comprising:
- mixing together a resin, a colorant, a wax, and an optional charge control agent to form toner particles in a first mixing step;
- mixing together a first inorganic fine powder and silicone oil to form an oiled inorganic fine powder in a second mixing step;
- and
- adding the oiled inorganic fine powder to the toner particles and mixing the oiled inorganic fine powder and toner particles together to form final toner particles, wherein no heat treatment is required to adhere the silicone oil to the inorganic fine powder.
