Abstract
Official abstract text for this publication.
A method for producing an electrophotographic photosensitive member including an undercoat layer includes preparing a coating liquid for an undercoat layer containing zinc oxide particles, a polyol, a blocked isocyanate compound whose isocyanate group is blocked with a specific structure, and a solvent mixture, in which the solvent mixture contains a monohydric alcohol in an amount of 1 chemical equivalent or more based on the specific structure and 90% by mass or less based on the total mass of the solvent mixture, and a ketonic solvent and/or a cyclic ether solvent in an amount of 7% by mass or more based on the total mass of the solvent mixture.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing an electrophotographic photosensitive member comprising a support, an undercoat layer formed on the support, and a photosensitive layer formed on the undercoat layer, the method comprising: preparing a coating liquid for an undercoat layer containing: zinc oxide particles; a polyol; a blocked isocyanate compound whose isocyanate group is blocked with a structure represented by the following formula (1); and a solvent mixture;…
