By finishing the rubber surface roughness to be smaller than that of the toner particles, we provide a developing roller that supports an even higher image quality. Longer rollers are also available for wide-format (A0, A1 size, etc.) machines.
In order to supply uniform toner to the photoconductor unit, the characteristics of rubber surface roughness and friction coefficient of the developing roller are very important. Yamauchi has the technology to control and match these characteristics to various types of toner. We also offer low-hardness ionic conducting material developed through our unique blending technology.
※For certain roller shapes, we can respond to needs for characteristics outside the above ranges. Contact Yamauchi for details.
