摘要: A developer used for an image forming apparatus including the step of forming a color image by using a single photoreceptor and removing a toner remaining on the photoreceptor after the transfer step with a cleaning blade, which developer is composed of a black toner having a circularity of 0.96 or less and a color toner having a circularity of 0.96 or more, in which at least inorganic particles containing Si compound particles and Ti compound particles are externally added to both of the black toner and the color toner, and the amount of the inorganic particles externally added to the black toner and the color toner satisfies the expressions (1) and (2). {Si(C)+Ti(C)}≧1.5×{Si(Bk)+Ti(Bk)} (1) Ti(C)≧1.5×Ti(Bk) (2)(In the expressions, Si(C), Ti(C), Si(Bk) and Ti(Bk) are as described in the specifications.)
