Title:
電子写真感光体の製造方法における検査方法
Document Type and Number:
Japanese Patent JP6682249
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an inspection method in a manufacturing method of an electrophotographic photoreceptor, the method capable of accurately determining, as a defect, film thickness unevenness of a second intermediate layer of the electrophotographic photoreceptor and a remnant film when part of the second intermediate layer is removed after applying the second intermediate layer.SOLUTION: An inspection method is used in a manufacturing method of an electrophotographic photoreceptor having a support medium, a first intermediate layer, a second intermediate layer, a charge generating layer and a surface layer in this order. The surface roughness (Rz) of the second intermediate layer/the surface roughness (Rz) of the first intermediate layer satisfies ≤0.9. The inspection method has an inspection step of inspecting a defect of the electrophotographic photoreceptor by an intensity difference of light detected, through irradiating the electrophotographic photoreceptor with light having a peak in a wavelength of 620-830 nm and the half band width of the peak being 10 nm or more, and detecting the light of 550-830 nm from among the reflectance of the light on the electrophotographic photoreceptor.SELECTED DRAWING: None
