The positively chargeable toner includes a binder resin and a coloring agent, the binder resin including (a) a resin (1) capable of forming a matrix in the toner, the resin (1) being a hybrid resin of a polyester resin and a vinyl resin; and (b) a resin (2) capable of forming a domain dispersed in the matrix formed by the resin (1), the resin (2) being a vinyl resin having a positive charge functional group. This positively chargeable toner has a good evenness of chargeability and a high charging-up speed with a small proportion of a reversely charged toner upon triboelectric charging. Moreover, in a heat roller fixing method, fixing at a low temperature can be performed without using an offset inhibiting liquid.
