ABSTRACT:
An image forming apparatus having an image bearing member having a substrate and a photosensitive layer having a charge generating layer and a charge transport layer, a charging device for uniformly charging the surface of the image bearing member, an irradiating device having a light source for irradiating the image bearing member to form a latent electrostatic image thereon, a developing device for developing the latent electrostatic image, a transfer device for transferring the developed image to a recording medium and a cleaning device for cleaning the surface of the image bearing member, wherein the charge transport layer contains a charge transport material represented by the following chemical formula, the light source emits light having a wavelength not less than 600 nm and the image bearing member is not irradiated with light having a wavelength less than 600 nm,wherein R1 and R2 independently denote a hydrogen atom, a substituted or non-substituted alkyl group, a substituted or non-substituted cycloalkyl group, a substituted or non-substituted aralkyl group, R3, R4, R5, R6, R7, R8, R9 and R10 independently denote a hydrogen atom, a halogen atom, cyano group, nitro group, amino group, hydroxyl group, a substituted or non-substituted alkyl group, a substituted or non-substituted cycloalkyl group, a substituted or non-substituted aralkyl group.
