Photoresponsive polymer

Abstract

[Object] An object of the present invention is to provide a photoresponsive polymer that sufficiently secures photoresponsiveness to be fluidized by light irradiation and reversibly non-fluidized, improves fixability, and further has good color reproducibility. [Solution] Provided is a photoresponsive polymer containing a structural unit derived from an azomethine derivative represented by the following general formula (1), the photoresponsive polymer being fluidized by light irradiation and reversibly non-fluidized: R1—Z1═Z2—R2  General formula (1): Z1 and Z2 are N or CH, while Z1≠Z2, R1 contains an aromatic hydrocarbon structure, R2 contains an aromatic heterocyclic structure, and a hydrogen atom is bonded to at least one carbon atom bonded adjacent to a carbon atom in the aromatic heterocyclic structure bonded to the Z2.
