摘要：
A carrier has a thermosetting silicone resin layer formed of a core particle and a thermosetting silicone resin on the surface of the core particle, and the thermosetting silicone resin layer is formed by subjecting a thermosetting silicone resin to a thermosetting treatment at a temperature lower than the melting point of a charge control agent contained in the thermosetting silicone resin layer, and includes an inner region which contains a positively chargeable charge control agent and an outer region which does not contain any positively chargeable charge control agent. The two-component developer containing the carrier as described above is charged into a developing device in an image forming apparatus to form an image.
