Black capable of achieving excellent solid black image quality with little variation in lightness even with a toner exhibiting stable development characteristics and exhibiting high image gloss and low temperature fixing characteristics regardless of use conditions Provide toner. A temperature (P1) at which a maximum value of a loss elastic modulus G ″ measured by a dynamic viscoelasticity test of a toner exists at 50 ° C. or more and 62 ° C. or less and a minimum value of a loss tangent tan δ is 120 ° C. or more and 155 The minimum value tanδ (P1) is 0.50 or more and 5.00 or less, and the storage elastic modulus value G ′ (P1) at P1 is 7.0 × 10 2 Pa or more and 1.0. × is the 10 4 Pa or less, G values of storage modulus at P1-20 ° C. If '(P1-20), the value of storage modulus at P1 + 20 ℃ G' was (P1 + 20), {LogG '(P1 −20) −LogG ′ (P1)} <{LogG ′ (P1) −LogG ′ (P1 + 20)}. [Selection figure] None |
