Abstract

A guiding opening is provided at the upper part of the side wall of a vertical conveying duct when the duct side wall extends horizontally. The upper end of the conveying auger 40 located in the vertical duct is bent sideward so as to be introduced into the guiding opening, and this introduced end portion is pivoted on the pivot portion. In such a manner, the end portion is rotatably pivoted and the other end is set free. Thus, developer introduced into the vertical conveying duct is carried thereinto in the axial direction of the conveying auger, and conveyed by rotation of the auger. Then, developer is exhausted in the axial direction.

Claims

1. An image forming apparatus comprising:

means for forming an image onto an image bearing member by providing image developing particles;

means for removing used image developing particles from the image bearing member;

means for collecting the removed developer particles;

means for guiding the removed developer particles to said collecting means, the guiding means being located between a first horizontal guide path and a second horizontal guide path, and substantially perpendicular to each said horizontal guide path, the guiding means receiving the developer discharged from the first horizontal guide path, the developer being conveyed to the second horizontal guide path by conveying means in the same direction as it is received;

means for conveying the removed developer particles in a predetermined conveying direction by rotating said conveying means, which is rotatably located in said guiding means;
