Processes for maintaining the triboelectric stability of electrophotographic developers |
| abstract |
A process for maintaining the triboelectric stability of an electrophotographic developer composition, comprising: n a. providing a first developer composition comprising first toner particles and virgin carrier particles; n b. determining the tribo product of said first developer composition; n c. providing an aged developer composition by subjecting said first developer composition to at least 5,000 electrophotographic imaging cycles, wherein the tribo product of said aged developer composition is from about 10 to about 200%·μC/g; n d. determining the tribo product of said aged developer composition; n e. providing a second developer composition comprising second toner particles and said virgin carrier particles; n f. incorporating said second developer composition into an electrophotographic imaging device; and n g. adding said first toner particles to said device as said second toner particles are depleted by image development; subject to the provision that the tribo product of said first developer composition is unequal to the tribo product of said second developer composition, and the tribo product of said first developer composition and the tribo product of said second developer composition are from about 10 to about 200%·μC/g. |
