機構の改良が求められている。However, in recent years,
The adhesive roller is pressed against the surface from which foreign matter is to be removed using a moving device such as an air cylinder. Some have been removed. However, with an adhesive roller equipped with a moving mechanism, it is difficult to control the pressing force on the foreign matter removing surface, that is, it is difficult to control the amount of movement of the moving mechanism in a minute amount. The positional deviation of the image receiving sheet and the transfer sheet fixed on the recording rotary drum may occur due to the increase in the adhesive force due to the excessive pressing force. Furthermore, due to the excessive pressing force of the adhesive roller against the sheet surface, the adhesion of the surface layer such as the image receiving layer and the cushion layer of the image receiving sheet in the middle of the conveyance, and the surface layer such as the color material layer and the light-to-heat conversion layer of the transfer sheet. Adhesive peeling frequently occurs. And
Every time a recording failure occurs due to the peeling of the image receiving sheet or the transfer sheet, etc., the recording apparatus must be stopped and work such as taking out the defective sheet or resetting the image receiving sheet or the transfer sheet must be performed. Transfer recording efficiency is not always good, and there is a need for an improved foreign matter removing mechanism using an adhesive roller.

The foreign matter is removed by pressing the recording drum 11 against the surface of the recording drum 11 or the surface of the sheet adsorbed and fixed on the recording drum.
The adhesive roller 15 is provided with a moving mechanism using an air cylinder, which moves in the direction of the recording rotary drum 10 when necessary, and not only removes foreign substances from the surface upon contact, but also starts the recording apparatus 1. It is also possible to adopt a configuration in which the recording rotary drum is rotated periodically even at the time of non-use when the power is turned on or when the power is not input, so that the foreign substances adhering to the surface of the recording rotary drum are removed. Finally, the image receiving sheet (R) is peeled off from the recording rotating drum 10 and is conveyed to a separate image transfer unit (not shown), and the toner ink on the image receiving sheet is further transferred to any printing paper. Thus, color printing for proofing is performed.

That is, if the rubber outer diameter is the same as the diameter of the regulating disc,
The pressure-sensitive adhesive member of the pressure-sensitive adhesive roller cannot be deformed by compression, so that the foreign matter is hardly peeled off on the surface where the foreign matter is to be removed, resulting in foreign matter removal failure. When transfer is performed in this state,
The presence of foreign matter causes image defects such as white spots and ring unevenness. On the other hand, when the diameter of the regulating disk is smaller than the outer diameter of the rubber by 0.5 to 2 (mm), the adhesive member is compressed and deformed and comes into close contact with the foreign matter removal target, so that a good foreign matter removing effect can be obtained. If the diameter of the regulating disk is smaller than the rubber outer diameter by 2.5 mm or 3 mm, the amount of compressive deformation (adhesion amount) of the adhesive member on the surface to be subjected to foreign matter removal becomes too large, and the image receiving layer of the image receiving sheet is peeled or transferred. Partial peeling of the toner layer of the sheet occurs, bending of the rotating shaft of the adhesive roller increases, and the like. When the surface to be removed is a recording medium surface fixing member (plate) for fixing the sheet placed on the recording rotary drum, or when the surface of the recording rotary drum or a mating roller is used, an adhesive member is used. Is large, the rotational resistance increases, and normal rotational movement is hindered.

もよい。As can be seen from Table 2, when the value of (R-r) / t is 0, the adhesion to the foreign matter removal target surface is very weak, and the foreign matter removal is poor, resulting in image defects such as white spots and ring umbra. It causes the occurrence. The value of (R−r) / t is 0.0
In the range of 5 to 0.5, the adhesion of the foreign matter was successfully removed in close contact with the transfer sheet and the recording drum. (R-r)
When / t is 0.6 or 0.7, the amount of compressive deformation of the adhesive member becomes too large, and the pressing force is unbalanced due to the peeling of the toner layer of the transfer sheet and the increase in the amount of deflection of the rotating shaft of the adhesive roller. In addition, the number of rotations of the drum has decreased due to an increase in the rotational resistance to the rotating drum for recording. Further, the recording medium fixing member is not limited to a cylindrical shape such as a rotary drum, but may have a planar shape and move in a horizontal direction with respect to a plane.

転写が行われることになる。As described above, the adhesive roller according to the present invention has a moving portion for pressing against the foreign matter removing surface and a cylindrical core having the adhesive member attached thereto. Providing a regulating disk having a small diameter and disposed outside the both end surfaces of the core, the adhesive roller moves and is pressed by the regulating disk when pressed against the surface to be subjected to foreign matter removal. By restricting the amount of compressive deformation of the adhesive roller, excessive pressing of the adhesive roller is prevented, and foreign matter adhering to the foreign matter removal target surface can be removed with a certain amount of compression of the adhesive member. As a result, image defects such as white spots and ring unevenness do not occur, and good image transfer is always performed.
