Abstract

To provide an electrophotographic developer, a method for manufacturing the same, and an image forming apparatus that can prevent an ATC sensor from erroneously measuring the concentration of toner in developer, and in turn can prevent the occurrence of fogging and toner scattering.SOLUTION: An electrophotographic developer having toner particles includes calcium oxide particles, aluminum hydroxide particles, and silica particles not subjected to hydrophobic treatment. The aluminum hydroxide particles are attached to the surface of the silica particle via physical adsorption or hydrogen bond.SELECTED DRAWING: Figure 1
