Toner

A toner comprising toner particles

• wherein
• each of the toner particles has a core-shell structure composed of a core and a shell phase formed on the core, the shell phase contains a resin (B), and the core contains a binder resin (A), a colorant and a wax,
• wherein
• the toner particles contain the resin (B) in an amount equal to or greater than 3.0 parts by weight and equal to or less than 15.0 parts by weight per 100.0 parts by weight of the core, and
• where a solubility parameter (SP value) of the binder resin (A) is denoted by SP(A) [(cal/cm3)1/2], an SP value of the resin (B) is denoted by SP(B) [(cal/cm3)1/2], an SP value of a repeating unit with the smallest SP value from among repeating units constituting the resin (B) is denoted by SP(C) [(cal/cm3)1/2], and an SP value of the wax is denoted by SP(W) [(cal/cm3)1/2],
• SP(A) is equal to or greater than 9.00 (cal/cm3)1/2 and equal to or less than 12.00 (cal/cm3)1/2,
• SP(W) is equal to or greater than 7.50 (cal/cm3)1/2 and equal to or less than 9.50 (cal/cm3)1/2,
• each of SP(A), SP(B), SP(C) and SP(W) satisfy relationships represented by Formulas (1) and (2) below:
• 0.00<{SP(A)−SP(B)}≦2.00 (1)
• 0.00<{SP(W)−SP(C)}≦2.00 (2), and
• the repeating unit with the smallest SP value from among the repeating units constituting the resin (B) is represented by General Formula (I) below:
• in General Formula (I), R1, R2 and R3 represent alkyl groups having a linear or branched chain with 1 to 5 carbon atoms, n is an integer from 2 to 200, R4 is an alkylene group having 1 to 10 carbon atoms, and R5 is a hydrogen atom or a methyl group.
