Publication number: 20150277366Abstract: A process cartridge includes an image holding body assembly that includes an image holding body, a developing assembly that includes a developer holding body, an urging member, a contacting and separating mechanism, and a gap forming mechanism. The image holding body assembly is inserted into and pulled from an assembly receiving portion. The urging member urges the developing assembly so that the developer holding body is pressed against the image holding body. The contacting and separating mechanism is disposed on the front side and operated to separate the image holding body assembly and the developing assembly from each other against an urging force. The gap forming mechanism forms a gap between the image holding body and the developer holding body on the rear side against the urging force. The size of the gap is larger than that existing before the image holding body assembly is pulled.Type: ApplicationFiled: September 16, 2014Publication date: October 1, 2015Applicant: FUJI XEROX CO., LTD.Inventors: Hideki KUGE, Toyohiko AWANO, Keisuke MORITA, Yoshiyuki TAKASHIMA, Kohyu SHIGEMORI, Masatoshi YAMADA
