摘要： When a grounded conductive roller touches a transfer drum through a transfer material while a voltage is applied to a conductor layer, charges having a polarity opposite to the polarity of the voltage applied to the conductor layer are generated over the transfer material, thereby making it possible to attract the transfer material to the dielectric layer. Since the voltage is applied to the conductor layer, the electrostatic attraction of the transfer material and the toner transfer can be carried out using a single power source. Moreover, since the attraction of the transfer material and the toner transfer are carried out by the charge injection, a lower voltage can be used. Thus, the voltage can be readily controlled while reducing the ozone emission to a relatively low level. Furthermore, since the toner transfer and electrostatic attraction of the transfer material can be carried out using a single power source, the apparatus can be downsized and less expensive. In addition, when a semiconductor layer is made of a solid elastic body, a high-quality transferred toner image can be obtained without image quality deterioration.
摘要翻译： 当接地的导电辊通过转印材料接触转印鼓，同时向导体层施加电压时，在转印材料上产生具有与施加到导体层的电压的极性相反的极性的电荷，从而使其成为可能 以将转印材料吸引到电介质层。 由于电压被施加到导体层，所以转印材料的静电吸引力和调色剂转印可以使用单个电源进行。 此外，由于转印材料和调色剂转印的吸引是通过电荷注入进行的，所以可以使用更低的电压。 因此，可以容易地控制电压，同时将臭氧发射降低到相对低的水平。 此外，由于可以使用单个电源进行转印材料的调色剂转印和静电吸引，所以可以使装置小型化并且成本更低。 此外，当半导体层由固体弹性体制成时，可以获得高质量的转印调色剂图像而没有图像质量劣化。

摘要： Ions are produced without causing any accompanying corona discharge by applying, to ion generation needles positioned so as not to contact a photoconductor drum, a voltage higher than or equal to an ion production threshold voltage and lower than a corona discharge threshold voltage. The photoconductor drum is charged by the ions produced. Accordingly, a charging device is provided which is capable of stable charging with high uniformity over a long period whilst reducing the production of ozone, nitrogen oxides, and other discharge byproducts.

摘要： An image-forming apparatus is provided with: a photoconductor drum having a surface on which a toner image is formed, a transfer drum for transferring the toner image onto a copying material by allowing the copying material to contact the photoconductor drum, and a ground roller for electrostatically attracting the copying material onto the transfer drum prior to transferring the toner image onto the copying material. The transfer drum is constituted by a semiconductive layer and a dielectric layer that are stacked on a conductive layer. Supposing that the nip width between the photoconductor drum and the transfer drum is L1, the rotation speed of the two drums is Vp, and the time constant, which is represented by a product of the resistance and the capacitance between the two drums, is τ, the relationship represented by L1/Vp
