    • A layered, positively-charged electrophotographic photoreceptor, a method for manufacturing the photoreceptor and an electrophotographic apparatus using the photoreceptor are disclosed. The layered, positively-charged electrophotographic photoreceptor includes a conductive support on which is provided a sequential stack composed of a charge transport layer containing at least a first hole transport material and a first binder resin; and a charge generation layer containing at least a charge generation material, a second hole transport material, an electron transport material, and a second binder resin, wherein the charge generation layer and the charge transport layer have a total amount of residual solvents that is 50 μg/cm2 or less. The photoreceptor is highly sensitive, highly durable, and has excellent image qualities including low image defects from cracks generated due to image memory or contact contamination. The photoreceptor is applicable to a high-resolution and high-speed positively-charged electrophotographic apparatuses and provides excellent operational stability.
