TONER, TWO-COMPONENT DEVELOPER, AND IMAGE FORMING METHOD
摘要:
A toner has a weight-average particle diameter (D4) of 3.0 μm or more and 8.0 μm or less, wherein the average circularity analyzed by dividing particles of the toner having an equivalent circle diameter of 1.98 μm or more and less than 200.00 μm into 800 in a range of a circularity of 0.200 or more and 1.000 or less is 0.960 or more and 0.985 or less, the proportion of particles A having a circularity of 0.990 or more and 1.000 or less is 25.0% or less on a basis of the number of particles, and the ratio of particles B having an equivalent circle diameter of 0.50 μm or more and less than 1.98 μm to the total particles having an equivalent circle diameter of 0.50 μm or more and less than 200.00 μm is 10.0% or less on a basis of the number of particles.
