Abstract:
There is provided a method of manufacturing a toner including a toner particle containing a binder resin, the method including: process 1: preparing a mixed solution including the following components i) to iii) in an aqueous medium: i) a particular silicon compound, ii) a fine particle having a number average particle diameter of 3 nm or more and 500 nm or less, and iii) a toner base particle containing the binder resin; and process 2: adjusting a pH of the mixed solution to 7.0 or more and 12.0 or less to condense the silicon compound, wherein the fine particle has an absolute value of zeta potential of 10.0 mV or more at the pH of the mixed solution of process 1.
