A toner contains a plurality of toner particles each including a core and a shell layer disposed over a surface of the core. The core contains a binder resin. The shell layer is substantially formed from a resin having at least one repeating unit including an alcoholic hydroxyl group (specific examples include a repeating unit derived from 2-hydroxyethyl acrylate, 2-hydroxy propyl acrylate, 2-hydroxyethyl methacrylate, and 2-hydroxy propyl methacrylate). A ratio of the repeating unit including the alcoholic hydroxyl group relative to all repeating units in the resin substantially forming the shell layer is at least 0.1% by mass and no greater than 20% by mass.
