A developer for a trickle developing method is used in formation of a full color image and is made of a mixture of a toner and a carrier. The toner contains inorganic fine particles as an internal additive and an external additive, a volume average particle diameter D50v of the toner is between 5.0 and 9.0 μm, a true specific gravity of the carrier is between 3.00 and 4.60, a volume average particle diameter of the carrier is between 15 and 60 μm, and the ratio of the volume average particle diameter of the carrier to the volume average particle diameter of the toner is between 3.00 and 7.00, and an image forming method using the developer. The developer for the trickle developing method prevents the embedding of the external additive in the toner by suppressing impact energy given by stirring the carrier and the toner in a developing device and a replenishment device of the developer, and has a resistance to toner degradation, an excellent transferability, a resistance to carrier contamination and a stable chargeability.
A developer for developing a full color image, which is replenished to a developing device to form a toner image and a part of which is discharged from the developing device to a discharge system, the developer comprising a toner and a carrier, wherein
