摘要： A developing device for electrophotographic image has a developing mechanism having a developer carrier for carrying a developer along a preset circulating route including a developing area and a developer restricting element for restricting the developer on the developer carrier, and a developer supply mechanism having a storing unit. The storing unit is filled with a start-up developer in the vicinity of the developer carrier and a replenishing developer remoter than the start-up developer from the developer carrier. The start-up developer and the replenishing developer have different grain sizes or grain size distributions. Further, a developing method for electrophotograhic image has the steps of using the start-up developer at an initial state of use of the developing mechanism, and using the replenishing developer differed in grain size or grain size distribution from the start-up developer after an end of the initial state of use of the developing mechanism.

摘要： A non-magnetic one-component developer is provided. This non-magnetic one-component developer includes toner particles and an external additive containing inorganic particles that adhere to the surface of each of the toner particles. In accordance with an emission analysis method utilizing fusion coupling plasma, the rate of free external additive that is determined by the ratio of the number of particles emitting light only from elements of the external additive to one toner particle is 9% or less by number. With such a non-magnetic one-component developer, the external additive will not be welded to the blade of a developing apparatus.
