摘要： A photoconductive image forming apparatus in which charged photoconductive toner contacts a transparent insulating substrate and is exposed from within the substrate. Exposure reduces the resistivity of the toner so that its charge can be reversed by a bias voltage and the exposed toner will adhere to the image forming substrate simultaneously with exposure and then transfer to a transfer medium. In an alternative embodiment of the invention, a layer of toner is applied to an electroconductive substrate and the toner layer is exposed with a latent image. The charge of the exposed toner is reversed and the exposed toner is removed by an intermediate toner removal device. The remaining toner is then transferred to a transfer medium. Toner suitable for use includes azo-type metal containing black dyes which do not absorb the exposure and can be sensitized to the near infrared region. Multicolor toners, each sensitized to a different exposure wavelength are provided so that a single multiple wavelength exposure and a single development can be used to form multicolor images.
摘要翻译：一种感光图像形成装置，其中带电的光电导调色剂接触透明绝缘基板并从基板内露出。曝光降低了调色剂的电阻率，使得其电荷可以通过偏置电压反转，并且暴露的调色剂将在曝光的同时粘附到成像基板上，然后转印到转印介质上。在本发明的替代实施例中，将一层调色剂施加到导电基底上，并且调色剂层用潜像曝光。曝光的调色剂的电荷反转，并且通过中间调色剂去除装置去除曝光的调色剂。然后将剩余的调色剂转移到转印介质。适合使用的调色剂包括不吸收曝光并且可以对近红外区域敏化的偶氮型金属黑色染料。提供每种对不同曝光波长敏感的多色调色剂，使得可以使用单次多波长曝光和单次显影来形成多色图像。

摘要： A non-magnetic single-component toner 8 of the present invention has toner mother particles 8a, and external additives 12 comprising: two hydrophobic silicas 13, 14 of which particle diameters are different from each other, i.e. a mean primary particle diameter of 7 nm to 12 nm and a mean primary particle diameter of 40 nm to 50 nm, and a hydrophobic rutile/anatase type titanium oxide 15 having a spindle shape of which major axial diameter is in a range from 0.02 nm to 0.10 nm and the ratio of the major axial diameter to the minor axial diameter is set to be 2 to 8, wherein the external additives 12 adhere to the toner mother particles 8a. By the hydrophobic silicas 13, 14 having work function smaller than the work function of the toner mother particles 8a, the negative charging property is imparted to the toner mother particles 8a and the fluidity is also insured. On the other hand, by mixing and using hydrophobic rutile/anatase type titanium oxide particles 15 having work function larger than or equal to the work function of the toner mother particles 8a together with the hydrophobic silicas 13, 14, the non-magnetic single-component toner 8 is prevented from excessively charged. Therefore, the amount of fog toner on non-image portions is reduced, the transfer efficiency is further improved, the charging property is further stabilized, and the production of reverse transfer toner is further inhibited.
