Filed: 1981-11-06
Abstract: PURPOSE:To obtain a double pipe having high grade of fitting easily by enclosing a pipe expanding medium in an inner pipe inserted into an outer pipe in a sealed-up state and expanding the inner pipe by applying a compressive force in axial direction of the inner pipe. CONSTITUTION:An end of threaded parts 5, 5 on both ends of a stainless steel inner pipe of specified diameter is stoppered with a cap 7 through a sealing material 6. The pipe is filled with water 8 that acts as a pipe expanding medium. Another end of the pipe is stoppered with a cap 7' through a seal 6. Under this condition, the inner pipe 2 is cooled with water by, for instance, submerging. The cooled inner pipe containing a pipe expanding medium 8 is inserted into an outer pipe 1 made of carbon steel having diameter enlarged by heating. Then, compression rods 10, 10' connected to a specified pressing device such as a hydraulic jack are brought in abutment on the caps 7, 7' on both ends of the inner pipe 2 and a pressure is applied to the caps. Consequently, the inner pipe is compressed in the axial direction. At the same time, the pipe is expanded by applying expanding force F caused by radial expansion of water 8 which is a compressible fluid. Thus, the inner pipe is brought in abutment on the outer pipe 1, and a strong self-tightening double pipe 11 is obtained.

Abstract: PURPOSE:To obtain uniform, stable and high-grade images free from uneven densities, etc., by laminating plural resin layers varying in contents of conductive materials, such as carbons, onto a base body of the developer carrying member, thereby forming the developer carrying member. CONSTITUTION:A developing sleeve 8 which is the developer carrying member consists of a metallic cylindrical pipe which is the metallic base body and the resin layers 6, 7 clad on the outer periphery of the base body.
