摘要： The present invention provides a method of producing an electrophotographic photosensitive member using a dispersion solution that shows high liquid stability in long-period storage and hardly causes aggregation of charge-transporting pigment particles during drying a coating. The method of producing an electrophotographic photosensitive member having a charge-transporting layer comprises a step of forming a coating film by applying a dispersion solution comprising polyolefin polymer particles and charge-transporting pigment particles as dispersoids and comprising a dispersion medium, and then forming the charge-transporting layer by heating the coating film and melting the polyolefin polymer particles, wherein the particles consisting of the polyolefin polymer particles and the charge-transporting pigment particles in the dispersion solution have a number average particle diameter of 50 nm or more and 300 nm or less and a degree of dispersion (standard deviation/number average particle diameter) of 1.0 or less.

摘要： An image forming apparatus including a latent image carrier and a developing means for charging a toner into a negative polarity by triboelectric charging, wherein the work function of the toner is set to be larger than the work function of the surface of the latent image carrier. When the apparatus includes an intermediate transfer medium, the work function of the toner is set to be larger than the work function of the surface of the intermediate transfer medium. In another embodiment, the work function ΦOPC of the surface of the latent image carrier, the work function Φt of the toner, and the work function ΦTM of the surface of the intermediate transfer medium are set to satisfy a relationship Φt>ΦOPC>ΦTM. These relationships help to reduce fog, and improve transfer efficiency which reduces the consumption of the toner.

摘要： A charge transport layer for an imaging member comprising a charge transport material with a nitrogen molecular defense system not exhibiting early onset of charge transport layer fatigue cracking. The nitrogen molecular defense system includes attaching bulky organic groups to charge transport materials. The bulky groups aid in preventing recrystallization of the charge transport molecule and shield the nitrogen from molecular attack, such as by oxidation. The charge transport layer exhibits excellent wear resistance, excellent electrical performance, and outstanding print quality.
