ABSTRACT:
An electrophotographic toner contains at least a binder resin and a colorant, and log10{[Cu]/[C]} satisfies the following equation (1):in-line-formulae description="In-line Formulae" end="lead"?−5.0≦log10{[Cu]/[C]}≦−3.5   (1)in-line-formulae description="In-line Formulae" end="tail"?in which, [C] represents a carbon content (%) and [Cu] represents a copper content (%), measured with fluorescent X-ray. An electrophotographic developer containing the toner, a method for producing the toner, and a method for forming an image by using the toner are also provided.
