Abstract
The invention provides a pressure contact roller for use in a recording paper feeding mechanism of a printer, the pressure contact roller is formed with crystalline resin powder projected from an outer circumferential surface of the roller body. By using the pressure contact roller, a printer is provided which can effectively prevent ink on the recording surface of a sheet of recording paper from drifting to the outer circumferential surface of the pressure contact roller, and can print high-quality full-color image free from unevenness in recording density.
Claims4
A pressure contact roller comprising a rod-like roller shaft and a substantially cylindrical roller body made of an elastomer material and formed over an outer circumference of said roller shaft, said pressure contact roller being held in pressure contact with a feed roller for advancing a sheet of recording paper to a recording position in a printer with roller rotation, thereby cooperatively feeding the sheet of recording paper while the sheet is gripped between both said rollers, wherein:
- said pressure contact roller is formed with crystalline resin powder projected from an outer circumferential surface of said roller body.
