Electrophotographic apparatus

Abstract

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 λa (nm) of the semiconductor laser, wavelength λb (nm) of the light-emitting diode and wavelength λc (nm) at which the electrophotographic photosensitive member has a maximum spectral sensitivity satisfy the following relationship (1):λa < λc < λb and any of the λa, the λb and the λc is within the range of from 380 nm to 520 nm.
