SOLUTION: The toner contains a binder resin and a colorant, wherein the binder resin contains a polyester (A) having a softening point Tm(A) of 120-160°C and a polyester (B) having a softening point Tm(B) of 80 to <120°C, obtained by polycondensing an alcohol component and a carboxylic acid component. The polyester (A) and/or (B) is a polyester obtained by polycondensing an alcohol component consisting substantially of only aliphatic alcohols in which≥65 mol% of 1,2-propanediol is contained in a dihydric alcohol component and a carboxylic acid component.
