More Information
Summary:A developer amount regulating member includes at least a portion for regulating the amount of a developer, which is made of a polyamide elastomer. The content of a polyamide dimer in the polyamide elastomer is decreased to less than 2500 ppm, thereby suppressing blooming of the oligomer component in long-term use or an environment of high temperature and high humidity, and maintaining the good specularity of the regulating member. Therefore, it is possible to prevent the problem of fogging due to blooming, and provide a high-quality image.
