PROBLEM TO BE SOLVED: To provide a toner capable of forming a high-definition image while achieving both transferability, fixing property and cleaning property. A toner comprising at least a binder resin and a colorant, wherein the toner has an average circularity of 0.95 or more, and a ground contact area (S) with respect to the total projected area (S) of the toner. The ratio (D / S) of D) is 15 to 40%, and the ground contact area (D) is the total area of the contact surface between the toner and the target surface. Toner. This toner has a shape capable of coming into contact with the latent image carrier with an appropriate contact area, exhibits a high transfer rate, and can prevent transfer dust.
