(57) [Summary] To develop a small particle size powder color toner excellent in chargeability, image density, resolution and the like. The average circularity ((perimeter of a circle having the same area as the projected area of a particle) / (perimeter of a projected image of a particle)) includes a colorant (A) and a binder resin (B) as essential components. (C) having a mean circularity of 0.98 or more, and a colorant (A) A powder color toner having a volume average particle size of 2 to 6 μm, wherein the content of the toner is 5% by weight or more based on the total weight of the binder resin (B) and the colorant (A). |
