摘要： A photoconductive image forming method in a which charged 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： 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.
