<p>PROBLEM TO BE SOLVED: To provide an electrostatic latent image developing black toner which is free of color rendering properties and has high stability of black, an image formed method using this toner and an image forming device using this toner. SOLUTION: This electrostatic latent image developing black toner exhibits the black by incorporating at least >=2 kinds among, for example, a yellow coloring agent, a cyan coloring agent and a magenta coloring agent and is obtained by polymerizing polymerizable monomers in an aqueous medium. The black toner preferably has external constitution by specific conditions. When the concentration of the yellow coloring agent contained therein is defined as Cy, the concentration of the cyan coloring agent as Cc and the concentration of the magenta coloring agent as Cm, the black toner preferably has the relations Cy>=Cc and Cy>=Cm and further when the concentration of the black coloring agent is defined as Ck, the black toner preferably has the relation Cy+Cc+Cm>=Ck.</p> |
