摘要：Electrophotographic apparatus having a blue (purple) semiconductor laser as a light source as an exposure means, an electrophotographic photosensitive member, a charging means, a developing means, a transfer means and a destaticizing means. The exposure means has a semiconductor laser and the destaticizing means having a light-emitting diode, wherein wavelength »a (nm) of the semiconductor laser, wavelength »b (nm) of the light-emitting diode and wavelength »c (nm) at which the electrophotographic photosensitive member has a maximum spectral sensitivity satisfy the following relationship (1): »a < »c < »b and any of the »a, the »b and the »c is within the range of from 380 nm to 520 nm.
