Abstract
A carrier for a two-component developer for developing a latent electrostatic image is composed of carrier particles, each of the carrier particles having a core particle and a coating layer provided on the surface of the core particle, with the coating layer containing an amino-group-containing modified silicone resin. A two-component developer is composed of a toner and the above-mentioned carrier.
Claims12
A carrier for a two-component developer for developing a latent electrostatic image, comprising:
- carrier particles, said carrier particles comprising
- a core particle, and
- a single coating layer provided on the surface of said core particle,
- wherein said single coating layer consists essentially of an amino-modified silicone oil and a resin modified silicone resin, and
- wherein an amount ratio by weight of said amino-modified silicone oil to said resin modified silicone resin is from (1:99) to (10:90).
