Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel and unlike attract. An object with an absence of net charge is referred to as neutral. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.
Electrophotographic photoreceptor, process cartridge, and image forming apparatus

The invention relates to an electrophotographic photoreceptor, a process cartridge, and an image forming apparatus. The electrophotographic photoreceptor includes a conductive substrate and a photosensitive layer of a single-layer type disposed on the conductive substrate. The photosensitive layer has an absorption coefficient of 0.008 or less at a wavelength of 1000 nm and contains a binder resin, a charge generating material, an electron transporting material, and a hole transporting material. The charge generating material is at least one selected from a hydroxygallium phthalocyanine pigment and a chlorogallium phthalocyanine pigment and is contained in an amount of 0.9% by weight or more and 1.8% by weight or less relative to the binder resin.
