Abstract

A two-component developerincludes a carrierand a toner. The carriersatisfies the relationships 100≤α≤220 and 300≤β≤480 when a voltage is applied in 1 V steps by a bridge resistance measurement method, where α (V) is a carrier voltage value obtained when a current value flowing through the carrierreaches 1.0(A), and β (V) is a carrier voltage value obtained when the current value reaches 1.0(A).
