PART-JOINED OBJECT, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To enhance the rigidity of a part-joined object obtained by abutting the outer peripheries of two or more resin parts to form a molten resin injection part in the abutted potion and injecting a molten resin in the molten resin injection part through the resin injection passage in one resin part to join container parts. SOLUTION: Spaces 154a and 154b crossing the paper surface of a drawing at a right angle are provided between the container parts 51 and 52 and spaces 154e and 154f are provided toward the interiors of the container parts 51 and 52 (joined to be formed into a toner container 50) from the spaces 154a and 154b. The molten resin is injected in the spaces 154a and 154e and the spaces 154b and 154f to join the container parts 51 and 52.
