    摘要： An electrophotographic photoreceptor of the present invention comprises a conductive support and a photosensitive layer. The photosensitive layer on the farthest side from the conductive support, includes a phenol derivative-containing layer which contains a phenol derivative having a methylol group and a charge transport material having at least one selected from the group consisting of a hydroxyl group, a carboxyl group, an alkoxysilyl group, an epoxy group, a thiol group and an amino group. An infrared absorption spectrum of the phenol derivative-containing layer satisfies the conditions represented by the following formula (1): (P2/P1)≦0.2  (1) P1 is an absorbance of a maximum absorption peak in a range of 1560 cm−1 to 1640 cm−1, and P2 is an absorbance of a maximum absorption peak in a range of 1645 cm−1 to 1700 cm−1.

    摘要： An electrophotographic photoreceptor that can sufficiently prevent occurrence of filming, whereby defects on an image can be sufficiently prevented, and an electrophotographic process cartridge and an electrophotographic apparatus using the electrophotographic photoreceptor are to be provided. The electrophotographic photoreceptor contains an electroconductive substrate having provided thereon a photosensitive layer, and an outermost layer of the photosensitive layer has a dynamic hardness of about from 13.0×109 to 100.0×109 N/m2. According to the invention, occurrence of flaws on the surface of the photoreceptor can be sufficiently prevented, and cracking of a member made in contact with the photoreceptor can also be sufficiently prevented. Therefore, occurrence of filming is sufficiently prevented, and occurrence of defects on an image is also sufficiently prevented.
