Process for producing toner |
摘要 |
A process for producing a toner with which toner particles can be highly conglobated, a toner that hardly causes fogging in an image, and an yield of toner is increased is provided. A process for producing a toner of the present invention comprises the step of simultaneously performing a surface modification and classification of particles by using a batch-wise surface modification apparatus, in which when a straight line extending from a central position S1 of a loading pipe in a direction of loading a raw material is denoted by L1 and a straight line extending from a central position O1 of the fine powder discharging pipe in a direction of discharging fine powder and ultra-fine powder is denoted by L2, an angle ¸ formed between the lines L1 and L2 is in a range of 210 to 330° with reference to the direction in which a classification rotor rotates.
