フトである。2. Description of the Related Art In office machines such as fax machines and printers, which carry a large amount of paper over a long period of time, printing paper is generally carried by a carrying roller 50 as shown in FIG. Target. Since the transport roller 50 transports a sheet by a frictional force generated between the roller and the sheet, the roller body 51 is often formed of a material having a high frictional force such as rubber and polyurethane in the related art. Reference numeral 52 is a metal shaft.

必要があるが、紙搬送に必要な表面摩擦力および耐磨耗
性の点から材質的に限界があった。However, in the case of the conveying roller 50 in which the roller main body 51 is made of an elastic material, the surface of the roller main body 51 is worn due to long-term and large amount of paper conveyance, and the hardness of the roller main body 51 increases when it is used at a low temperature. As a result, the frictional force is reduced, which may cause a paper conveyance failure. Moreover, the elastic body has a problem that it is difficult to obtain high dimensional accuracy. In addition, the contact width between the paper and the roller 50, which is one of the important requirements regarding the conveyance of the paper (refers to the width along the conveyance direction of the paper, called the nip)
In order to sufficiently secure the above, it is necessary to make the roller main body 51 to have a low hardness, but there is a limit in terms of material in terms of the surface friction force and abrasion resistance required for paper conveyance.

ことができる。According to the carrying roller 60, the ceramic particles 63 on the surface bite into the paper, so that the paper can be reliably carried. In addition, the ceramic particles 63
Has a high abrasion resistance and does not change its shape due to a temperature change, so that the durability of the roller 60 itself becomes high and a stable paper carrying force which is not influenced by temperature can be obtained.

Since the roller body 61 is made of a rigid metal body and is not deformed, it is difficult to sufficiently secure the nip. Therefore, it is necessary to supplement the nip shortage by separately providing a mechanism for giving a high pressing force to the transport roller 60, such as providing a backup roller in addition to the transport roller 60, and the structure becomes complicated, The load on the motor for rotating the motor increases, and the design load increases.

ある。SUMMARY OF THE INVENTION The present invention has been proposed in view of the above problems, and can secure a sufficient nip without providing a special mechanism such as a backup roller and has high abrasion resistance. It is an object of the present invention to propose a conveyance roller that has the property of being stable, is less affected by temperature changes, and can stably and reliably convey slippery paper.

A roller body having a circular cross section through which the shaft is inserted, an elastic layer provided on the outer peripheral surface of the roller body, and ceramic particles attached to the outer peripheral surface of the elastic layer via a binder. The present invention relates to a characteristic transport roller.

るニップが充分なものになる。The transport roller rotates while the ceramic particles on the surface bite into the paper, and thus has a large gripping force on the paper and reliably transports the paper. Also, since the elastic layer exists between the ceramic particles and the roller body,
The elastic layer is elastically deformed by the pressing of the conveying roller against the paper, so that the nip for the paper on the surface of the conveying roller becomes sufficient.

分が補われて紙搬送が確実になされる。Moreover, since the ceramic particles have little change in hardness with temperature and are excellent in abrasion resistance, the paper can be stably conveyed over a long period of time with little influence of temperature. Further, even if the ceramic particles are worn and the grip force is reduced, the elastic layer inside the ceramic particles ensures a sufficient nip as described above, and therefore the decrease in the grip force is caused. It is supplemented and the paper is transported reliably.
