TONER FOR ELECTROPHOTOGRAPHY |
摘要 |
<p>This invention provides a toner for a method for image formation by electrophotography, particularly a toner that, in a one-component development method, has stable fluidity and electrostatic properties for a long period of time, is free from image defects, and is also excellent in transferability and transfer efficiency. The toner for electrophotography comprises matrix toner particles and at least titanium oxide fine particles and fluidizer fine particles deposited on the surface of matrix toner particles. The titanium oxide fine particles are spherical and have an average primary particle diameter of 200 to 400 nm. The fluidizer fine particles have a specific surface area of 60 to 250 m<SUP>2</SUP>/g.</p> |
