Title: Resistance irregularity measuring method and inspection method
Inventor: KANEKO CHIEMI
IPC: G03G21/00
Filed: 2000-10-13
Abstract: PROBLEM TO BE SOLVED: To stably supply a transfer device and an image forming device or the like where the deterioration of image quality is restrained to be little by inspecting a transfer brush which should be manufactured so that resistance irregularity at an upstream side part in a transfer material carrying direction may be different from that at a downstream side part therein. SOLUTION: The transfer brush 10 is manufactured so that the resistance irregularity at the upstream side part 10A in the transfer material carrying direction may be less than that at the downstream side part 10B in that direction. Before mounting the transfer brush in the transfer device 2, an electrode 15 is brought into contact with the part 10A of the transfer brush, and a current value is measured while moving the electrode 15 to which 2 kV voltage is applied in a width direction. The current value is measured at the part 10B similarly to the part 10A. Then, the transfer brush whose maximum current value at the upstream side part is <=10 μA and whose maximum current value at the downstream side part is 70 μA is regarded as a non-defective.  Therefore, the transfer brush where excessive current at the upstream side part influencing the deterioration of the image quality hardly flows is selected and only such a transfer brush is mounted in the transfer device or the like.
