摘要:
A toner for electrophotography, including a release agent; a binder resin; a colorant; and an external additive, wherein the binder resin is a polyester resin, and wherein the toner has a loss on heat not greater than 0.40% by weight at 165° C. and a difference between a loss on heat at 200° C. and the loss on heat at 165° C. not greater than 0.50% by weight, and includes a n-paraffin in an amount not less than 3% by weight.
摘要:
A magenta toner, produced by a method including suspending an oily liquid comprising a binder resin and a colorant in an aqueous medium, wherein the colorant comprises a naphthol pigment and a quinacridone pigment, and the quinacridone pigment comprises a pigment having a specific formula.
摘要:
A toner containing a binder, a colorant, and a wax having a molecular chain consisting of C—H bond and C—C bond, wherein the mass reduction of the wax at 165° C. is 10% by mass or less, and the total amount of the wax in the toner measured by a DSC method is 1% by mass to 8% by mass, wherein a ratio, Sbet/SF, of a BET specific surface area (Sbet) of the toner to an average circularity (SF) of the toner is 1.0 m2/g or more to less than 3.6 m2/g, wherein the toner is obtained through a process which contains at least emulsifying or dispersing a toner material liquid in an aqueous medium containing a surfactant, and wherein the toner material liquid is a liquid containing toner-forming materials which contains at least the binder, the colorant and the wax.
摘要:
A full-color image forming method, including: developing an electrostatic latent image with a two-component developer, including: a toner including: a binder resin, a colorant, and a layered inorganic mineral in which ions between its layers are at least partially modified with an organic ion; and a carrier, wherein the toner includes a black, a yellow, a magenta and a cyan toner and the carrier is formed of a magnetic particulate material coated with a resin, wherein each of the toners are contained in each toner cartridge comprising the carrier, from which the two-component developer is fed into each image developer developing each of the electrostatic latent image and discharging the extra developer therefrom, and wherein each of the toners has a aerated apparent density not greater than 0.40 and a difference of the aerated apparent density between each of the toners is not greater than 0.10.
摘要:
