Abstract:
1. A toner, comprising: a binder resin comprising a polyester resin A and a polyester resin B which are different from one another; and a colorant, wherein polyester resin A is obtained by condensation polymerization of a linear saturated aliphatic dicarboxylic acid having 4 to 12 carbon atoms and a linear saturated aliphatic diol having 2 to 12 carbon atoms and polyester resin B comprises a bisphenol skeleton, and wherein the toner has a glass transition temperature by differential scanning calorimetry (DSC) of 20° C. or greater and less than 50° C., an endothermic peak temperature by DSC of 50° C. or greater and less than 80° C. and an amount of compressive deformation at 50° C. by thermomechanical analysis of 5% or less.
