The present invention relates to an electrophotographic photoreceptor having extremely high uniform sensitivity over a wide range of Lm.

(abbreviated as CGM), vi, monomaso dyes, dismazo dyes, and sulfinic acid derivative dyes soluble in organic monosulfur compounds (lrf 1985-55643), quinocyanine pigments (Japanese Patent Laid-Open No. 53-42830) , copper phthalocyanine pigment (JP-A-51-11763), and tellurium arsenide amorphous selenium (JP-A-50-15137), amorphous selenium (JP-A-50-15137), etc.
Inorganic substances such as No. 2-75392) have also been proposed. On the other hand, in recent years, many X-type metal-free 7-thalocyanines and single-dye sensitized organic substances have been proposed as CGMs sensitive to near-infrared light (wavelengths of 750 nm or more).

Another disadvantage is that a light source having a wavelength in the CGM absorption wavelength range must be used.
