DEVELOPER SUPPLYING BODY, DEVELOPING CARTRIDGE, IMAGE FORMING DEVICE AND METHOD FOR WORKING DEVELOPER SUPPLYING BODY

摘要

PURPOSE: To obtain an image without a void in a longitudinal stripe state caused by a toner supply roller. CONSTITUTION: The toner supply roller 12 is constituted of a core bar 12a and urethane sponge 12b carried on the surface of the core bar 12a. By arranging a nichrome wire 40 near the urethane sponge 12b and rotating the roller 12 while applying heat, a whisker-like matter left after grinding on the surface is burnt off. Thus, a situation that the chip powder being the whisker-like matter left after grinding is held between a developing roller 11 and a developing blade 13 and the longitudinal white stripe is caused is prevented.
