Problems solved by technology

The result is a reduction in availability or an increase in costs due to an increase in parts due to the construction of the conveyor rollers that can be replaced
[0007] In addition, when utilizing the existing separation pad to separate and convey the recording paper sheets, as the number of separated and conveyed sheets of the recording paper sheets increases, the paper dust generated from the surface of the recording paper sheets adheres to the surface of the separation pad, causing the conveying rollers to Recording sheet refeeding due to reduced friction
Therefore, there are the same problems as in the case of conveying rollers

Abstract

The present invention provided a sheet processing member, and sheet transporting device and image processing device using the same, which can prevent decrease in frictional force caused by the attachment of paper powder and to realize a roller member an the like of high durability. A sheet transporting roller kept into contact with a sheet for transporting the sheet by frictional force, has a plurality of fine projections 22 of a height of 1 [mu]m-500 [mu]m on a contact face with the sheet, and each projection 22 has a spherical part 22b on a tip of its uprising part 22a uprising from the contact face.

Description

technical field [0001] The present invention relates to a sheet acting member such as a conveying roller for conveying a sheet in contact with a sheet by its frictional force, or a separation pad for separating a sheet, a sheet conveying device using the sheet, an electrophotographic copier, a printer, a word processor Image processing devices such as machine and facsimile devices. Background technique [0002] In recent years, image forming apparatuses such as printers and copiers employing electrophotography and other recording methods have become popular. Therefore, along with improvement in performance and life of the apparatus, the conveyance accuracy and durability of the conveyance roller used in the image forming apparatus must be improved. In addition, the separation accuracy and durability of the separation pad used in the image forming apparatus must also be improved. [0003] Here, if Figure 8 As shown, the existing conveying roller 100 includes metal and a sh...
