Abstract
A toner includes a crystalline polyester resin in an amount equal to or greater than 25% by mass. The toner satisfies the following formula when the toner is tested using a capillary rheometry measurement during which a pellet of the toner is pressed by a member while being heated: 0.3≤(first temperature−second temperature)/(second temperature−third temperature)≤1, where the first temperature is a temperature at which the member falls 4 mm, the second temperature is a temperature at which the member falls 2 mm, and the third temperature is a temperature at which the member starts to fall.
