摘要：
An image forming toner is provided, including at least: a binder resin; a colorant; and a release agent, wherein a volume-average particle diameter of the toner measured by a Coulter counter is from 5 to 8 µm; the content of the toner having a volume-average particle diameter of not greater than 5 µm is 60 to 75 % by number; and the content of the toner having a number-basis circle-equivalent particle diameter of from 0.6 to 3 µm measured by a flow-type particle image analyzer is not greater than 25 %.
