摘要：
A toner includes a base particle; and an external additive covering the base particle. The toner includes a tetrahydrofuran (THF)-insoluble component having a glass transition temperature determined from a DSC curve when heated for the second time of from −50° C. to 10° C. and an average circularity not greater than 0.98, and satisfies the following relation: Bt−0.025×Ct≦1.80 wherein Bt represents a BET specific surface area [m2/g]; and Ct represents a coverage [%] of the external additive covering the base particle.
