Abstract:
1. A partially imidized polyamic acid composition comprising: a conductive carbon black; and a partially imidized polyamic acid obtained by a polymerization and imidization reaction of a diamine compound, a tetracarboxylic acid dianhydride, and an acid monoanhydride at a quantitative ratio satisfying the following Relational Expression (1) and Relational Expression (2): wherein, in Relational Expressions (1) and (2), X represents a content by mol of the diamine compound, Y represents a content by mol of the tetracarboxylic acid dianhydride, and Z represents a content by mol of the acid monoanhydride, the partially imidized polyamic acid has an imidization ratio of from 4.1% to 25.0%, and a main molecular skeleton of the polyamic acid is represented by the following Formula (1):
