Abstract
A two-component developer includes a toner and a carrier. The toner includes a plurality of toner particles. The carrier includes a plurality of carrier particles. Each of the toner particles includes a toner core and a shell layer disposed over the surface of the toner core. The toner has a charge decay constant of at least 0.020 and no greater than 0.050 as measured with the toner particles in an external additive-free state. The carrier has a volume resistivity of at least 1.0×10Ω·cm.
