TONER

To provide a toner that has a charging property less affected by a moisture and has an excellent low-temperature fixation property.SOLUTION: The toner includes: toner mother particles containing a binder; and particles (A) of a copolymer formed of a composition unit based on a hydrophobic monomer (a) and a composition unit based on at least one type of monomer (b) selected from the group of a carboxy group-containing monomer and a sulfonic acid group-containing monomer, the rate of the composition unit based on the hydrophobic monomer (a) to the sum of the total composition unit being 98-99.7% by mass, the rate of the composition unit based on the monomer (b) to the sum of the total composition unit being 0.3-2% by mass, and the weight average molecular amount being 10,000 to 200,000, and the content of the particles (A) being 0.3-10 parts by mass to 100 parts by mass of the binder.SELECTED DRAWING: None 【課題】帯電性が湿度の影響を受けにくく、低温定着性に優れるトナーを提供する。【解決手段】結着剤を含むトナー母粒子と、疎水性単量体（ａ）に基づく構成単位と、カルボキシ基含有単量体及びスルホン酸基含有単量体からなる群から選ばれる少なくとも１種の単量体（ｂ）に基づく構成単位とからなり、全構成単位の合計に対する前記疎水性単量体（ａ）に基づく構成単位の割合が９８〜９９．７質量％、前記単量体（ｂ）に基づく構成単位の割合が０．３〜２質量％であり、重量平均分子量が１０，０００〜２００，０００である共重合体の粒子（Ａ）と、を含み、前記粒子（Ａ）の含有量が、前記結着剤１００質量部に対して０．３〜１０質量部である、トナー。【選択図】なし
