Abstract
An electrophotographic photoreceptor includes a conductive substrate and a single-layer photosensitive layer which is provided on the conductive substrate and contains a binder resin, at least one charge generating material selected from a hydroxygallium phthalocyanine pigment and a chlorogallium phthalocyanine pigment, a first electron transporting material defined in the specification, a second electron transporting material defined in the specification, and a hole transporting material defined in the specification, wherein a total content of all electron transporting materials is greater than or equal to 4 parts by weight with respect to 100 parts by weight of a total solid content of the photosensitive layer, and an average loss elastic modulus E″ of the photosensitive layer, which is obtained by measuring dynamic viscoelasticity at a temperature of from 35° C. to 50° C. and a frequency of 0.5 Hz, is less than or equal to 1.000×10.
