The 2nd Belt Transfer Roller is composed of metal core and elastic rubber coated with metal core. Its specific structure is roughly as follows:

1. The charging roller is tightly wrapped with a low-hardness conductive elastic layer outside the metal core, and a surface layer is coated outside the elastic layer. The thickness of the surface layer is very thin, about several to tens of microns, and the resistance is high.
2.2nd Belt Transfer Roller has only low hardness conductive elastic layer outside the metal core, but the outer surface is specially treated.
3. The charging roller is a surface layer outside the low-hardness conductive elastic layer, and the surface layer is a rubber tube with high resistance, with a thickness ranging from tens of microns to 1 mm.
4.2nd Belt Transfer Roller has a uniform electric layer between the low-hardness conductive elastic layer and the surface layer, the thickness of the electric layer is 1-3μm, and the thickness of the surface layer is 40-80μm.
The charging roller is a surface layer outside the low-hardness conductive elastic layer, and the surface layer is a rubber tube with high resistance, with a thickness ranging from tens of microns to 1 mm. The entire 2nd Belt Transfer Roller is evenly charged and has stable performance during use, providing a good guarantee for printed products.
