Patent ID: 6855469

Claim:
A full-color image-forming method comprising: a charging step of charging an electrostatic-image-bearing member electrostatically; a latent-image-forming step of forming an electrostatic latent image on the electrostatic-image-bearing member having been charged; a developing step of developing the electrostatic latent image by the use of a developer held in a developing assembly, to form a toner image; a transfer step of transferring to a transfer material the toner image having been formed; and a fixing step of fixing the toner image to the transfer material, said developer used in said developing step comprising a plurality of color developers and a black developer, said color developers being each a two-component developer for full-color image formation which has i) a color toner having color toner particles containing at least a binder resin, a colorant and a wax and ii) a carrier for the color developer, said black developer being a two-component developer for full-color image formation which has i) a black toner having black toner particles containing at least a binder resin, carbon black and a wax and ii) a carrier for the black developer, each of said color toners and said black toner are charged with the same polarity in said developing step, and said carrier for the black developer having a larger absolute value of charge quantity when the same toner is used, than the respective carriers for the color developers.
