    摘要： A developer contains a set of color toners and black toner for use in a full color image forming apparatus. Each of the color toners contains a color colorant and a first binder resin, and the black toner contains a black colorant and a second binder resin. The difference between softening point and flow starting temperature of said first binder resin is less than the difference between softening point and flow starting temperature of said second binder resin.
