Abstract
A photoconductor including: a conductive support; an undercoat layer; and a photoconductive layer, the undercoat layer being disposed over the conductive support, the photoconductive layer being disposed over the undercoat layer, wherein the undercoat layer includes zinc oxide particles, wherein when a film thickness of the undercoat layer is 20 μm, the undercoat layer has transmittance of 50% or more to light having a wavelength in a range of 500 nm or more but 800 nm or less, wherein a lowest transmittance of light is 85% or less in the range, and wherein when an electric field of 5 V/μm is applied to the undercoat layer, volume resistivity of the undercoat layer is 1.0×107 Ω·cm or more but 5.0×108 Ω·cm or less at an environment of 23° C. and 55% RH.
