本発明は特に半導体レーザー用として適した酸化亜鉛系

高感度電子写真感光体は殆んど矧られていない。Recording devices such as laser printers that use laser light to form electrostatic latent images require electrophotographic photoreceptors that are highly sensitive to laser light. For such a high-sensitivity electrophotographic photoreceptor, for laser light such as VIS-argon laser (wavelength 488 and 515 nm (Z) long wavelength light in the visible range), zinc oxide, acid enhancer such as rose bengal or erythrosine is used. Books are known that have been spectrally sensitized by adding a sensitizing dye. However, semiconductor lasers (wavelengths of 700 to 1000) are smaller and cheaper than argon lasers.
There are almost no high-sensitivity electrophotographic photoreceptors that are suitable for visible to near-infrared long-wavelength light (nm visible to near-infrared long wavelength light).
本発明の目的は波長700〜1000 nmの長波長光
に対し高感度を有し、従って元導体レーザー用として好
適な電子写真感光体を提供することである。An object of the present invention is to provide an electrophotographic photoreceptor that has high sensitivity to long wavelength light in the wavelength range of 700 to 1000 nm and is therefore suitable for use in a base conductor laser.

傾向を有する。The electrophilic compound used in the present invention is used as a spectral sensitizing aid, and specific examples thereof include benzoquinone, chloranil, phthalic anhydride, dinitrobenzoic acid, and tetracyanoquinodimethane. A suitable amount is 0.02 to 0.5% Fi for the amount of zinc oxide used. If the amount used is less than 0.02% by weight, the sensitizing effect tends to decrease, but this is thought to be due to poor adsorption of the dye represented by the above general formula to zinc oxide. Moreover, if the amount used is more than 0.5% by weight, there is a tendency that the dark decay becomes faster and the sensitizing effect becomes worse.

A photoconductive layer forming liquid in which an electron-affinity compound, a dye of the above general formula, and a resin are dissolved or dispersed in an organic solvent such as toluene may be coated and dried.

In this case, zinc oxide is added to a solution containing the electron-affinity compound and dispersed, and then the dye (or its solution) of the general formula (or its solution) and the resin (or its solution) are added by evaporating the solvent or without evaporating the solvent. It is preferable to prepare a photoconductive layer forming solution in addition to the 11th step.

Monochromatic light (by xenon lamp spectroscopy) of 10 nm
The attenuation of the blush potential was measured by irradiating at an interval of , and from this the sensitivity was determined as half Ift, the reciprocal of the amount of light in m. The results are shown in the table below along with the measurement wavelength. Note that both photoreceptors are 70
Photosensitivity to long wavelength light of 0 to 950 nm was observed.

感光体のl/lO以下であった。In Examples 1 to 7, electrophotographic photoreceptors were prepared in the same manner as in Examples 1 to 7, except that no electron-affinity compound was used, and therefore the zinc oxide was not surface-treated with the compound. When the sensitivities were determined, they were lower than l/lO of the photoreceptors of Examples 1 to 7, respectively.
