Claim:
1. A toner comprising: toner particles each including a surface layer that contains an organic silicon polymer, the organic silicon polymer including a unit represented by formula (1) or (2) below: (in formula (2), L represents a methylene group, an ethylene group, or a phenylene group), wherein, in a chart obtained by (in formula (Q3), R F represents one of structures represented by formulae (i) to (iv) below: (in formulae (i) to (iv), * represents a bonding portion that bonds to the silicon atom, and in formulae (ii) and (iv), L independently represents a methylene group, an ethylene group, or a phenylene group)), and wherein a silicon concentration at surfaces of the toner particles determined by electron spectroscopy for chemical analysis conducted on the surfaces of the toner particles is 2.5 atomic % or more.
