Abstract
A method for manufacturing an electrophotographic photoconductor including a charge generating layer and a charge transport layer in this order on a cylindrical electrically-conductive support including the steps of: (i) immersing the support in a charge generating layer coating liquid, (ii) pulling the support out of the coating liquid, (iii) heat drying the support coated with the coating liquid to form the charge generating layer, (iv) cooling the charge generating layer, and (v) immersing the support on which the charge generating layer has been formed in a charge transport layer coating liquid while retaining gas inside of the support. The charge transport layer coating liquid contains a solvent having a boiling point of 34° C. or more and 85° C. or less, and the step (v) satisfies two specific conditions.
