A toner having good low-temperature fixability, charge stability, environmental stability, and durability and capable of stably producing high-quality images for a long time is provided. The toner includes a toner particle having a core-shell structure constituted of a core and a shell phase. The core contains a binder resin, a colorant, and wax, and the shell phase contains a resin A. The resin A is a comb polymer including a main chain portion (X), a side chain portion (Y), and a side chain portion (Z). The main chain portion (X) is a vinyl polymer, the side chain portion (Y) has an aliphatic polyester structure and has an ester group concentration of a polyester segment of 6.5 mmol/g or less, and the side chain portion (Z) has an organic polysiloxane structure and has an average number of Si-O bond repeating units of a siloxane segment of 2 or more and 100 or less. |
