In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings, and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. The inverse of the wavelength is called the spatial frequency. Wavelength is commonly designated by the Greek letter lambda (λ). The term wavelength is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids.
Electrophotographic photoreceptor, process cartridge, and image forming apparatus
InactiveCN107870527ASuppress ghostingHigh sensitivityElectrographic process apparatusEngineeringPhthalocyanine
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.
