ROLLER HAVING ELASTIC LAYERS FOR TRANSFERRING A PRINT IMAGE |
| 摘要 |
A roller for transferring a print image or a toner layer onto another element in a printer or copier is provided. The roller can include a base body, a first elastic layer applied onto the base body and a second elastic layer applied onto the first elastic layer, wherein the ratio of the moduli of elasticity of the elastic layers and/or the ratio of the thicknesses of the elastic layers are matched to one another so that the average surface velocity difference between the roller and the other element is reduced and/or minimized. |

1. A roller for transferring a print image or a toner layer between the roller and another element in a printer or copier, the roller comprising:
a base body; a first elastic layer applied onto the base body; and a second elastic layer applied onto the first elastic layer, wherein at least one of: a modulus of elasticity of the first elastic layer and a modulus of elasticity of the second elastic layer, and a thickness of the first elastic layer and a thickness of the second elastic layer, are matched to one another such that an average surface velocity difference between the roller and the other element is minimized. |
