Manufacturing method for electrophotography photosensitive body

A method for manufacturing an electrophotography photosensitive body, comprising the steps of:

• forming at least a charge generation layer on at least a conductive substrate;
• said charge generating layer using a first coating solution containing at least a first charge generating substance, a first binding resin, and a first solvent;
• forming at least a charge transport layer on top of said charge generation layer;
• said charge transport layer using a second coating solution containing at least a second charge transport substance, a second binding resin, and a second solvent;
• said second solvent being of a type effective to prevent a dissolution of said charge generation layer into said charge transportation layer during said step of forming at least a charge transport layer;
• said second solvent being a mixture solvent;
• and
• said mixture solvent containing at least 1, 3 dioxolane and toluene, whereby said dissolution is minimized.
