電子写真用感光体、その製造方法およびそれを搭載した電子写真装置

Japanese Patent JP7346974

B2

An electrophotographic photoconductor includes a conductive substrate; and a photosensitive layer provided on the conductive substrate and containing a charge generation material, a hole transport material, a first electron transport material, from 3% by mass to 40% by mass of a second electron transport material, a resin binder, and an inorganic oxide filler surface-treated with a silane coupling agent. In a dipole-dipole force component (a Hansen solubility parameter), the first electron transport material and the silane coupling agent have a difference of ΔSPa<2.50; the second electron transport material and the silane coupling agent have a difference of ΔSPb<2.50; and the first electron transport material and the second electron transport material have a difference of 0.30<ΔSPc<1.00. In a London dispersion force component (a Hansen solubility parameter), the resin binder and the silane coupling agent have a difference of ΔSPd<2.00.
