Abstract
Provided is a toner having a toner particle including a binder resin and a colorant, wherein the toner has a softening point of at least 100° C. and not more than 150° C., and when Tgt represents a glass transition temperature (° C.) of the toner during a second temperature rise as measured with a DSC, Tgf represents a glass transition temperature (° C.) of a tetrahydrofuran-insoluble matter of the binder resin during a second temperature rise as measured with a DSC, and Tgk represents a glass transition temperature (° C.) of a tetrahydrofuran-soluble matter of the binder resin during a second temperature rise as measured with a DSC, the toner satisfies Tgt>Tgf (1), Tgt>Tgk (2), and 35° C.≤Tgf≤70° C. (3).
