Abstract
The present invention relates to a binder carrier comprising at least magnetic particles and a binder resin. The binder resin contains a thermoplastic silicone-modified acrylic resin which is a copolymer of a polydiorgano-siloxane macromer having an acrylic functional group and a radical-polymerizable organic monomer. The binder carrier of the present invention a long-life binder carrier which eliminates the possibility of carrier deterioration due to toner components, such as a charge-controlling agent and an after-treatment agent, and which is less liable to deteriorate in its chargeability.
