Abstract
Toners are provided which may be suitable for use in cold fusing pressure apparatus. The toners include low molecular weight amorphous resins having low softening points and low molecular weights, compared with resins utilized in conventional emulsion aggregation toners for low melt fusing applications.
Claims20
A toner comprising:
- at least one low molecular weight amorphous resin having a molecular weight of from about 500 to about 10000 daltons;
- at least one crystalline resin;
- at least one wax;
- and
- an optional colorant,
- wherein the at least one low molecular weight resin possesses a softening point of from about 90° C. to about 105° C. and a glass transition temperature of from about 50° C. to about 60° C .
3 more elements
A toner comprising:
- at least one low molecular weight amorphous polyester resin having a molecular weight of from about 500 to about 10,000 daltons;
- at least one crystalline polyester resin;
- at least one wax selected from the group consisting of polyethylene, polypropylene, and polybutene, and combinations thereof;
- and
- an optional colorant,
- wherein the at least one low molecular weight resin possesses a softening point of from about 90° C. to about 105° C., and a glass transition temperature of from about 50° C. to about 60° C.
3 more elements
An electrophotographic machine comprising:
- a developer unit comprising toner for developing a latent image, wherein said toner comprises an emulsion aggregation toner comprising at least one low molecular weight amorphous polyester resin having a molecular weight of from about 500 to about 10,000 daltons, a softening point of from about 90° C. to about 105° C., and a glass transition temperature of from about 50° C. to about 60° C., in combination with at least one crystalline polyester resin, at least one wax, and an optional colorant;
- and
- a fuser member for fusing said toner to a flexible substrate via application of pressure of from about 1000 psi to about 10,000 psi.
