ABSTRACT:
An image forming apparatus contains a photoconductor having a support and a photoconductive layer disposed thereon. I(S) at the surface of the photoconductor and I(S) at the interface of the photoconductive layer on the support side are 5.0×10−3or less and the sum of I(S)s is 3.0×10−3or more. I(S)s are determined according to following Equations 2 and 3 after subjecting a group of data of N samples of height x(t) [μm] of a profile curve at the surface or of one at the interface to discrete Fourier transform according to following Equation 1, the N samples being taken at intervals of Δt [μm] in a reference line direction.X⁡(nN·Δ⁢⁢t)=∑m=0N-1⁢⁢x⁡(m·Δ⁢⁢t)⁢exp⁡(-ⅈ2π·nN·Δ⁢⁢t·m·Δ⁢⁢t)Equation⁢⁢1wherein n and m are each an integer; N is 2ρ, where ρ is an integer.S⁡(nN·Δ⁢⁢t)=1N·X⁡(nN·Δ⁢⁢t)2Equation⁢⁢2I⁡(S)=(1N)⁢∑n=0N-1⁢⁢{S⁡(nN·Δ⁢⁢t)}.Equation⁢⁢3
