  Here, details of image formation on the recording medium 100 of the embodiment by the image forming apparatus 10 will be described. As described above, the recording medium 100 according to the embodiment includes the circuit device 102 having the storage member 104 therein and is formed of a plurality of layers. The recording medium 100 is conveyed to the image forming apparatus. The width X in the direction orthogonal to the width is formed to be wider than that of a recording medium provided with a conventional circuit device.

  Hereinafter, a case where the recording medium 100 is conveyed from the manual feed unit 80 into the image forming apparatus main body 12 will be described. At this time, the recording medium 100 is disposed so that the coating layer 108 side on which an image is formed faces the lower side, that is, the manual feed unit 80 side.

  When the image forming apparatus 10 forms an image on the recording medium 100 according to the embodiment, the recording medium 100 is arranged in the manual feed unit 80 as described above. At this time, the recording medium 100 is arranged such that the wide width X side of the recording medium 100 is fed. That is, the wide width X side of the recording medium 100 is parallel to the direction orthogonal to the transport direction of the transport path 56 of the image forming apparatus 10, and the width X side of the recording medium 100 faces the transport direction of the transport path 56 of the image forming apparatus 10. Placed in.

  When forming an image on the recording medium 100 of the embodiment, in the image forming apparatus 10, the width X side of the recording medium 100 is parallel to the conveyance direction of the conveyance path 56 of the image forming apparatus 10. When the recording medium 100 is arranged so that the narrow width side of the recording medium 100 is parallel to the image forming apparatus 10, for example, the conveyance of the recording medium is stopped or the image is formed. Or may be canceled.

  When the recording medium 100 is transported from the manual feed unit 80 into the image forming apparatus main body 12, as described above, the recording medium 100 is sent out by the manual pickup roll 82, and is rolled by the manual feed roll 84 and the manual retard roll 86, and the transport roll 88 is led to the main transport path 56a. Thereafter, after being guided to the main conveyance path 56 a, the recording medium 100 is sent from the registration roll 58 to the transfer device 24.

  Then, as shown in FIG. 4A, the recording medium 100 is transferred to the recording medium 100 by the developer 130 transferred to the transfer member 38 by the secondary transfer roll 42 as shown in FIG. 4A. Transcribed.

  At this time, as shown in FIG. 4B, when transferring to a recording medium 300 having a width Z narrower than the width Y of the secondary transfer roll 42 and narrower than the width X of the recording medium 100 of the embodiment, the secondary transfer roll The electric charge 130 applied to the recording medium 300 by 42 escapes to the member 38 to be transferred, and the electric charge necessary for the image formation disappears, causing a problem in the image formation.

  This is because when the recording medium 300 passes between the secondary transfer roll 42 and the transferred member 38, the resistance value of the recording medium 300 is compared with the resistance value of the transferred member 38 in the portion where the recording medium 300 does not pass. This is because the charge 130 applied to the recording medium 300 leaks to the transfer member 38.

  That is, when the recording medium 300 is on the member 38 to be transferred, the total resistance value of the portion through which the recording medium 300 passes is the sum of the resistance value of the recording medium 300 and the resistance value of the member 38 to be transferred. Since the total resistance value of the portion through which the recording medium 300 does not pass is only the resistance value of the transferred member 38, the resistance value of the portion through which the recording medium 300 passes does not pass through the recording medium 300, and the charge 130 of the recording medium 300 increases. This is because the ink leaks to the transferred member 38 in a portion where the adjacent recording medium 300 does not pass.

  Furthermore, in the case of the recording medium 100 according to the embodiment in which the circuit device 102 is disposed inside, a base material layer 110 formed of a resin material is provided on the surface side on which an image is formed, or a coating layer In addition, for example, white film processing or the like may cause a structure in which charges are more likely to leak than paper materials such as ordinary recording paper, so that charges can escape more easily in a narrow recording medium 300. Become.

  At this time, if a high charge is applied to the narrow recording medium 300 so that a sufficient charge remains even if the charge escapes for transfer, a safety device provided in the image forming apparatus is activated. As a result, the application of the transfer voltage stops, and as a result, sufficient charges cannot be obtained, resulting in problems in image formation.

  On the other hand, as shown in FIG. 4A, the recording medium 100 according to the embodiment having a wide width has a width X in a direction orthogonal to the conveyance direction of the conveyance path 56 and the width Y of the secondary transfer roll 42. The width is the same or approximate, that is, the width Y of the secondary transfer roll or less and 70% or more of the width Y. Therefore, even if the charge 130 applied to the recording medium 100 leaks to the transfer member 38, the charge 130 for forming an image is sufficiently left, so that a problem in image formation is prevented. can do.

  Note that the width Z of the recording medium 300 narrower than the width X of the recording medium 100 according to the embodiment is 70% or less of the width Y of the secondary transfer roll 42, and the charge 130 leaks from the recording medium 300. Increases, and it is easy for problems to occur in image formation.

  Next, referring to FIGS. 5 and 6, the set voltage when the recording media 100, 400, and 500 having different widths are passed between the secondary transfer roll 42 and the transferred member 38 of the image forming apparatus 10 is described. An experiment on the difference in the measured voltage will be described.

  As shown in FIG. 5, the recording medium used in the experiment uses the recording medium 100 according to the embodiment as a wide recording medium, and the width is 315 mm (see FIG. 5A). Further, as a comparative recording medium, an experiment was performed using a recording medium 400 having a width of 210 mm (see FIG. 5B) and a recording medium 500 having a width of 105 mm (see FIG. 5C). The width Y of the secondary transfer roll 42 used in the experiment is 350 mm (the maximum width of the usable recording medium is 330 mm).

  As a result, as shown in FIG. 6, the recording medium 100 of the embodiment, that is, the recording medium 100 having a wider width, has actually measured a voltage close to an ideal line compared to the recording media 400 and 500 having a smaller width. It has become so.

  Therefore, since the wide recording medium 100 can hold more charges than the narrow recording media 400 and 500, the recording medium 100 according to the wide embodiment is different from the narrow recording media 400 and 500. In comparison, it is possible to prevent problems in image formation.

  In addition, after passing the secondary transfer roll 42 of the transfer device 24, the recording medium 100 is discharged to the discharge unit 16 after the image is formed as described above.
