Abstract

A toner receiving member, which is open upward, is provided at a position vertically below a lower end of a contact surface between a side seal member and a developing roller. The toner receiving member can receive and store toner which has leaked. In addition, when a developing cartridge is removed from a main body casing and then placed on a horizontal surface such as a desktop, a front wall, which serves as a bottom surface of the toner receiving member, faces upward. Toner collected in the toner receiving member may be prevented from leaking.

Description

[0001] Cross-reference of related applications [0002] This application claims priority to Japanese Patent Application 2004-285162 filed on September 29, 2004, the entire subject matter of which is incorporated herein by reference. Technical field [0003] The invention relates to a processing box and an imaging device containing the processing box. Background technique [0004] The electrophotographic image forming apparatus may be provided with a process cartridge including a developing device. The process cartridge is designed to be detachably attached to the main body of the image forming apparatus. The process cartridge includes a housing that stores toner as a developer and a developing roller, and the developing roller is rotatably installed in an opening formed in the housing. The developing roller is designed to form a visible image by transferring a thin layer of toner formed on the developing roller to an electrostatic latent image formed on the photosensitive drum. Th...
