Patent ID: 6921617

Claim:
A method for forming images using a plurality of developers to form a multicolored image, comprising the steps of: charging a photoreceptor; forming an electrostatic latent image by exposing the photoreceptor surface; forming a black toner image by developing an electrostatic latent image using a developer containing a toner comprising a black color toner particle having a colorant concentration of 4 to 15%; transferring the black color toner image onto a transfer body; forming a white toner image by developing the electrostatic latent image using a developer containing a toner, wherein the toner for developing an electrostatic latent image includes: a white color toner particle containing at least a binder resin and a colorant, with the particle having a volume average particle diameter of no greater than 14 μm and a concentration of the colorant being 20 to 50% by weight with respect to the binder resin, wherein a ratio of white color toner particles having a particle diameter of no greater than 4 μm is 6 to 16% by number with respect to the total number of the white toner particles; and an external additive containing a hydrophobic titanium oxide particle having a BET specific surface area of 40 to 250 m 2 /g; wherein the absolute charge value of the toner is 20 to 50 μC/g; and transferring the white toner image onto the black toner image.
