PROBLEM TO BE SOLVED: To provide a fixed image which is high in gloss and is suppressed in the occurrence of glossiness unevenness. SOLUTION: The toner contains toner particles of a weight average molecular weight of 20,000 to 35,000 and is Gt(190)≥35% when a solid part of 4.0 g/m<SP>2</SP>is made on paper of a basis weight 104 g/m<SP>2</SP>by using the toner and when the glossiness of the solid part fixed at 190°C by JIS Z 8741:97 at the time the solid part is fixed onto the paper by bringing the solid part into contact for 40ms with a heating member of an image fixing device is defined as Gt(190), 0.8≤Gt(189)/Gt(190)≤1.2 is satisfied when the glossiness of the solid part fixed at 180°C is defined as Gt(180).
