摘要： An image forming apparatus including a consumable to be used for image formation. The image forming apparatus includes: a usage amount detector configured to detect a cumulative value of a usage amount of the consumable and a remaining amount of the consumable; a predictor configured to predict a period that allows use of the consumable based on the remaining amount detected by the usage amount detector; and a determination unit configured to generate a delivery request signal for prompting a delivery request for the consumable when the period that allows the use predicted by the predictor is smaller than a predetermined number-of-day threshold value. The image forming apparatus avoids performing processing for generating a delivery request signal by the determination unit after the start of the use of the image forming apparatus until a predetermined condition is satisfied.

摘要： 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.
