摘要:
A toner includes an amorphous resin; and a crystalline polyester resin dispersed in the amorphous resin. The crystalline polyester resin has a volume-average particle diameter (Dv) of from 0.07 to 0.20 μm, and a ratio (Dv/Dn) of the volume-average particle diameter (Dv) to a number-average particle diameter (Dn) thereof of from 1.00 to 2.25.
