Abstract: An image forming apparatus and an image forming method are provided which form high-quality fixed images having no fogs and the like defects, in which apparatus and method a toner entering a pressure-contact area between rollers is prevented from scattering. A control is performed on preheating conditions for preheating an unfixed toner image on a recording medium, which unfixed toner image indicates a toner image transferred but not yet fixed, and a control is further performed such that an amount of toner attached to the recording medium at a coverage rate of 100% is 0.4 mg/cm2 or less, with the result that the toner is prevented from scattering when the recording medium carrying the unfixed toner image passes through a pressure-contact area formed between a heating roller and a pressurizing roller in a fixing step.

Abstract: A method for manufacturing a capsule toner, capable of obtaining a capsule toner including a coating layer having uniform thickness at high yield is provided. The method for manufacturing a capsule toner includes a fine resin particle adhering step of adhering fine resin particles to surfaces of toner base particles, a spraying step of spraying a spray liquid for plasticizing the toner base particles and the fine resin particles, while fluidizing the toner base particles and the fine resin particles, and a film-forming step of fluidizing the toner base particles and the fine resin particles until the fine resin particles adhered to the surfaces of the toner base particles are softened to form a film. In the spraying step, ultrasonic vibration is applied to set a number average liquid-droplet diameter of the spray liquid to less than 10 μm.
