Electrophotographic photoreceptor, process cartridge and image forming device using the same

A process cartridge integrally comprising:

• an electrographic photoreceptor comprising a photosensitive layer and a surface layer laminated on a conductive substrate in this order;
• and
• at least one selected from a charging device, a development device or a cleaning device,
• the surface layer comprises a group 13 element and oxygen, and absorption peak intensities showing bonds other than a bond between the group 13 element and oxygen are 0.1 times or less of an absorption peak intensity showing a bond between the group 13 element and oxygen in an infrared absorption spectrum in a range of 4000 cm−1 to 400 cm−1.

An image forming device comprising:

• an electrographic photoreceptor comprising a photosensitive layer and a surface layer laminated on a conductive substrate in this order;
• a charging device for charging a surface of the electrographic photoreceptor;
• an electrostatic latent image forming device for forming an electrostatic latent image on the charged electrographic photoreceptor;
• a development device for developing the electrostatic latent image as a toner image with a developer comprising a toner;
• and a transfer device for transferring the toner image onto a recording medium,
• the surface layer comprises a group 13 element and oxygen, and absorption peak intensities showing bonds other than a bond between the group 13 element and oxygen are 0.1 times or less of an absorption peak intensity showing a bond between the group 13 element and oxygen in an infrared absorption spectrum in a range of 4000 cm−1 to 400 cm−1.
