摘要： The present invention provides an electrophotographic photoconductor which can reduce the generation of fogging under a high-temperature and high-moisture condition and can be easily manufactured, and a method of manufacturing such an electrophotographic photoconductor. In an electrophotographic photoconductor which includes a support base body, an intermediate layer and a photoconductor layer and a manufacturing method of such an electrophotographic photoconductor, the intermediate layer contains titanium oxide and a binding resin and a ΔL value of the intermediate layer satisfies a following relationship formula (1) or a ΔA value of the intermediate layer satisfies a following relationship formula (2), that is, −5.0≦ΔL≦0 (1) and ΔA≦0.055 (2), wherein the ΔL value is a value which is obtained by subtracting an L value (a parameter value which is measured by a color-difference meter in accordance with JIS Z 8722) which is measured with respect to a single support base body from the L value which is measured in a state that the intermediate layer is formed on the support base body, and the ΔA value is a value which is obtained by subtracting reflection absorbance (a parameter value which is measured by a color-difference meter) which is measured with respect to a single support base body from the reflection absorbance which is measured in a state that the intermediate layer is formed on the support base body.
