摘要:
A method of fixing toner in a belt fixing unit having a fixing roller; a heating roller; an endless fixing belt binding the heating roller and the fixing roller under tension therebetween; a pressure roller disposed to face the fixing roller intervening the fixing belt; and a fixing heater disposed inside one of the pressure roller and the heating roller, the method of fixing includes: a step for fixing a toner image on an image fixing material by conveying the toner image on the image fixing material in between a portion of the fixing belt not touching the fixing roller and the pressure roller; featured by the toner particle being spherical having a roundness of 0.96 or more and contains a colorant and resin component containing a modified polyester resin.
摘要:
A dry toner contains fine particles having average sphericity of 0.93 to 0.99, a content of the fine particles having a particle diameter of 2 μm or less in the dry toner is 20% by number or less. A method for manufacturing a dry toner includes a process for dispersing in an aqueous medium containing water and a water-soluble organic solvent, a toner composition contained in an organic solvent by using fine solid dispersing agent; and a process for contracting volume of the dispersed toner composition. Further, the image forming apparatus having a photoconductor; a charger for charging the photoconductor; a light irradiator for irradiating the electrophotographic photoconductor to form a latent electrostatic image; a developer for developing the latent electrostatic image to form a developed image; and a transfer for transferring the developed image to a recording material, and the developer contains the dry toner abovementioned.
