CONDUCTIVE FOAM ROLL FOR ELECTROPHOTOGRAPHIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a conductive foam roll for an electrophotographic apparatus that forms a uniform urethane foam layer to improve performance to scrape off a toner.SOLUTION: There is provided a conductive foam roll 10 for an electrophotographic apparatus that comprises a shaft body 12 and a conductive foam layer 14 arranged on the outer periphery of the shaft body 12, where the conductive foam layer 14 is formed of a polyurethane foam containing a metal salt represented by the following formula (1) as a maximum component of an ion conductive agent and satisfies the relationship of the following formula (2). (1) (FSO)N M wherein M is one of K and Li. (2) (σ/μ)×100≥50, wherein μ is the average diameter of a cell and σ is the standard deviation of the diameter of a cell.SELECTED DRAWING: Figure 1
