摘要： Provided are a method of producing an electrophotographic photosensitive member, particularly, a method of producing an electrophotographic photosensitive member and an organic device by which, in a method of forming a charge transporting layer, the stability of an application liquid for the layer after long-term storage is improved while the usage of an organic solvent in the application liquid is curtailed, and the layer having high uniformity is formed. The method is a method of producing an electrophotographic photosensitive member which includes a support and a charge transporting layer formed thereon, the method including: preparing a solution including: a first liquid whose solubility in water under 25°C and 1 atmosphere is 1.0 mass% or less; a second liquid whose solubility in water under 25°C and 1 atmosphere is 5.0 mass% or more; a charge transporting substance; and a binder resin; preparing an emulsion by dispersing the solution in water; forming a coat for the layer on the support by using the emulsion; and forming the layer by heating of the coat.

摘要： Disclosed is a charge-transporting compound represented by the formula (1) below which is composed of a polymer having a polymer main chain wherein fluorene derivatives are connected at the 9-position which fluorine derivatives are respectively substituted by an amino group having an aromatic ring or a heterocyclic ring. By using such a charge-transporting compound in the charge-transporting thin film, an organic EL device can be operated at a low voltage and is able to have a high luminance, long life while being free from defects.
