Developer and image forming method

摘要

The present invention provides a developer suitable for a hybrid developing device which may provide a high-quality clear image by suppressing the occurrence of a ghost phenomenon, the occurrence of a carrier-jumping phenomenon and the occurrence of a current leaking phenomenon, and an image forming method which uses such a developer. In a developer which is used for a hybrid developing device which includes a developer transporting body for charging the developer containing carrier and toner while holding magnetism and a developer carrying body for transferring the toner thereto from the transporting body and for forming a thin toner film on a surface thereof, and which is for applying a developing bias to the developer carrying body so as to form a latent image of a latent image carrying body, a specific resistance of the carrier is set to a value which falls within a range of 1x10⁹ to 1x10¹² Omega.cm, the saturation magnetization of the carrier is set to a value which falls within a range of 36 to 60 emu/g, and a specific resistance of the toner is set to a value which falls within a range of 1x10¹³ to 1x10¹⁶ Omega.cm.
