Title: Developing roller, developing device and image forming device
Inventor: MURAKAMI EISAKU
IPC: G03G15/08
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To enhance the developing quality of an electrostatic latent image by preventing the electric resistance value of a developing roller from being varied. SOLUTION: An electrical conductive elastic roller part 11 formed at the outside circumferential part of the core bar 7 of the developing roller 1 is constituted of an inner layer 8, a surface layer 9 and an intermediate adhesive layer 10 making the layers 8 and 9 adhere. Since the uniform electric resistance value in the layer 10 is regulated to be smaller than the electric resistance value of the layer 8, the electric resistance value varied in the layer 8 is uniformized to the fixed electric resistance value in the layer 10 even when the electric resistance value of the layer 8 is varied. Therefore, since the electric resistance value of the roller part 11 of the roller 1 is prevented from being varied, the electric resistance value of the roller 1 is uniformized as the result. Thus, the developing quality of the electrostatic latent image is enhanced.
