Abstract

PURPOSE: To improve mechanical fixation and electrical conduction between a conductive porous elastic material and a core metal circumference by fitting the elastic material around the core metal circumference with a specified pressure.
CONSTITUTION: Pipe-shaped body 3 consisting of a conductive porous elastic material of polyethylene, polyurethane, or the like, made conductive by mixing in a given amount of a conductive material, such as carbon powder or metal powder is fitted around the outer circumference of roller-shaped core metal 1' and used as an elastic roller for developing, fluid squeezing, and cleaning. At that time, body 3 is made at 10W40 in ASKER C-type hardness, the ratio of the outer diameter of metal 1' and the inner diameter of body 3, etc. are properly adjusted, and a pressure of 10W 500g/cm2 is applied to the circumference for pressure fitting, thus, permitting the contact between metal 1' and body 3 to be sufficient, and the conduction between both 1', 3 to be kept satisfactory.
