    • Support structures for containing and supporting components forming a digital copier are configured with square pipes and are provided separately in association with a plurality of units of the digital copier. The effect of distortion is eliminated when the support structures are joined to maintain positional accuracy. Square pipes are combined to form each of a first support structure for containing and supporting various components forming the digital copier, for example, an image forming process portion and a fixing portion and a second support structure for containing and supporting various components to be incorporated therein as needed, for example, a sheet supplying portion. To combine the first and second support structures, square pipes and square pipes orthogonal to each other are joined in the regions of joining surfaces. This makes it possible to prevent, for example, distortion and twisting between the supporting structures.

    • The present invention is made to provide a pretransfer charging device, which allows (i) reduction of generation of discharge products such as ozone and nitroxide, (ii) excellent uniform charging, (iii) continuous stable charging for a long period of time, and (iv) restraint of distortion of a toner image. The pretransfer charging device includes (i) ion generation needles each provided face to face with an image carrier such as a photoconductor drum or an intermediating transfer belt, and (ii) a high-voltage power supply for applying a negative voltage to each of the ion generation needles. The voltage to be applied from the high-voltage power supply is not less than an ion production threshold voltage but is less than a corona discharge threshold voltage. With this, no corona discharge occurs but negative ions can be generated. This makes it possible to solve various problems caused due to the corona discharge.
    • 本发明提供一种预转印充电装置,其能够(i)减少诸如臭氧和氮氧化物的放电产物的产生,(ii)优异的均匀充电,(iii)长时间连续稳定充电,以及 (iv)限制调色剂图像的变形。 预转印充电装置包括:(i)各离子产生针各自与诸如感光鼓或中间转印带的图像载体面对面地设置,以及(ii)高压电源,用于向 离子生成针。 从高压电源施加的电压不小于离子产生阈值电压,但小于电晕放电阈值电压。 由此,不会发生电晕放电,而是会产生负离子。 这使得可以解决由于电晕放电引起的各种问题。
