摘要

[Problem] To provide: a method for forming a light receiving layer, which enables stable production of an organic photoelectric conversion element having excellent after-image current characteristics; a method for producing an organic photoelectric conversion element; an organic material for film formation; an organic photoelectric conversion element which is obtained using this organic material for film formation; and a photosensor. [Solution] A method for forming a light receiving layer (30) of an organic photoelectric conversion element (1) that is used in a photosensor by means of a dry film-forming process. In this method, an organic material (60) for film formation, which is formed of an organic material that constitutes the light receiving layer (30) and is composed of a particulate material having a fluorescence quantum yield of 0.2 or more, is prepared, and then a dry film-forming process is carried out using a vaporization source that contains the organic material (60) for film formation.
