Abstract
A developer set includes a first developer as a two-component developer stored in a developing device from beginning of use of the developing device, and a second developer as a two-component developer stored in a replenishment container connected to the developing device, so as to be replenished to the developing device after starting use of the developing device. When a saturation magnetization of the carrier in the first developer is Sc, a resistance of the carrier in the first developer is R, and a content of the carrier with respect to toner of the second developer in the replenishment container is Cc, then 28<Sc×log10 R×Cc<120 is satisfied.
Claims7
A developer set to be used for developing an electrostatic latent image by a developing device, the developer set comprising:
- a first developer as a two-component developer stored in the developing device from beginning of use of the developing device;
- and
- a second developer as a two-component developer stored in a replenishment container connected to the developing device, so as to be replenished to the developing device after starting use of the developing device, wherein
- when a saturation magnetization of a carrier in the first developer is Sc, a resistance of the carrier in the first developer is R, and a content of the carrier with respect to toner of the second developer in the replenishment container is Cc, then 28<Sc×log10 R×Cc<120 is satisfied.
