A photoreceptor including a support and a photosensitive layer formed thereon, optionally an undercoat layer between the support and the photosensitive layer, wherein when a group of data consisting of N samples of the height x(t) (μm) of a profile at the interface of the support on the side of the photosensitive layer, the interface of the photosensitive layer on the side of the support, and/or the interface of the undercoat layer on the side of the photosensitive layer, measured perpendicular to a horizontal direction of the support, taken at Δt (μm) intervals in the horizontal direction, is subjected to Fourier transformation in accordance with a formula as specified in the specification, in a power spectrum obtained by the Fourier transformation, I(S) represented by a formula specified in the specification has a particular value, a method of evaluating the above photoreceptor, a method of producing the photoreceptor, and an image formation apparatus in which the photoreceptor is incorporated are disclosed.
An image formation apparatus comprising a photoreceptor which comprises a support and a photosensitive layer formed thereon, wherein when a group of data of N samples of the height x(t) (μm) of a profile at the interface of said photosensitive layer on the side of said support, measured perpendicular to a horizontal direction of said support, taken at Δt(μm) intervals in said horizontal direction, is subjected to Fourier transformation in accordance with formula (1):
An image formation apparatus comprising a photoreceptor which comprises a support, an undercoat layer formed on said support, and a photosensitive layer formed on said undercoat layer, wherein when a group of data of N samples of the height×(t) (μm) of a profile of the surface of said undercoat layer on the side of said photosensitive layer, measured perpendicular to a horizontal direction of said support, taken at Δt(μm) intervals in said horizontal direction, is subjected to Fourier transformation in accordance with formula (1):
