Abstract:
1. An image forming apparatus comprising: an image bearing member configured to bear a latent electrostatic image, the image bearing member comprising a substrate and a photosensitive layer comprising a charge generating layer and a charge transport layer, wherein the charge generating layer comprises titanyl phthalocyanine; a charging device configured to uniformly charge a surface of the image bearing member; an irradiating device comprising a light source, the irradiating device configured to irradiate the image bearing member to form a latent electrostatic image on the image bearing member; a developing device configured to develop the latent electrostatic image with a toner; a transfer device configured to transfer the developed image to a recording medium; a cleaning device configured to clean the surface of the image bearing member; and a discharge device comprising a discharge light source configured to irradiate the surface of the image bearing member with discharge light having a wavelength not less than 600 nm from between the transfer device and the charging device, wherein the charge transport layer comprises at least one charge transport material represented by at least one compound selected from the group consisting of wherein the light source emits light having a wavelength not less than 600 nm and the image forming apparatus is configured such that the image bearing member is not irradiated with light having a wavelength less than 600 nm, and wherein the titanyl phthalocyanine has a spectroscopic having a CuKα X-ray diffraction spectrum having a wavelength of 1.542 Å such that a maximum peak is observed at a Bragg (2θ) angle of 27.2±0.2°, main peaks at a Bragg (2θ) angle of 9.4±0.2°, 9.6±0.2° and 24.0±0.2°, and a peak at a Bragg (2θ) angle of 7.3±0.2° as a lowest angle diffraction peak, and having no peak between 9.4±0.2° and 7.3±0.2°.
