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.

摘要： The present invention provides a toner which ensures large mean charging amount and excellent transfer efficiency with no or little amount of reversely charged toner and provides an image forming apparatus using the same. The toner is produced by adding external additives to resin particles containing a coloring agent, wherein the external additives are silica particles and modified silica particles of which outer surfaces are modified with oxide or hydroxide of at least one metal selected from a group consisting of titanium, tin, zirconium, and aluminum, the amount of the modified silica particles being 1.5 times or less of the amount the silica particles. The image forming apparatus uses the toner.

摘要： By causing the movement of charge from a toner to a latent image carrier, the amount of charge of the toner is lowered to an amount of charge suitable for facilitating the transfer of toner so as to improve the transfer efficiency. For this, an image forming apparatus comprises a latent image carrier (1) and a developing means (4) for forming a negatively chargeable toner layer composed of two stories or less on a toner carrier (10) by a toner layer thickness regulating member (9), wherein an electrostatic latent image on the latent image carrier is developed with the toner to form a visible image and the visible image is transferred to a transfer medium (5), and is characterized in that the work function (Φ opc ) of the surface of the latent image carrier (1) is set to be larger than the work function (Φ t ) of the toner.
