Hereinafter, the present invention will be described in detail. The toner of the present invention is a toner including toner particles having a surface layer containing an organosilicon polymer, and the organosilicon polymer has a partial structure represented by the following formula (1) or (2). And
In X-ray photoelectron spectroscopic analysis of the surface of the toner particles, the surface of the toner particles, the concentration of carbon atoms dC, the concentration of oxygen atoms dO, and the total concentration dSi of the silicon atoms when the 100.0 atomic% , the concentration dSi of the silicon atoms is at 22.2 atomic% or less 1.0 atomic% or more,

本発明に係るトナー粒子は、JIS B0601:2001に基づいて測定される粗さ曲線要素の平均長さをRSm1とし、前記トナー粒子をスクロース溶液中で遠心分離にかけて、前記トナー粒子の表面への付着力が小さい粒子を分離除去したトナー粒子の、粗さ曲線要素の平均長さをRSm2としたとき、RSm2/RSm1が、1.20以下であることが好ましい。 The toner particles according to the present invention have an average length of a roughness curve element measured based on JIS B0601: 2001, RSm1, and the toner particles are centrifuged in a sucrose solution to attach the toner particles to the surface of the toner particles. when the toner particles where the particles-adhesive strength is less separated was removed, and the average length of roughness curve element and RSM2, RSM2 / RSm1 is preferably 1.20 or less.
通常、トナー表面の粒子が一部外れた状態であるRSm2の値は、RSm1に比べて大きくなる。RSm2/RSm1が大きいほど、トナー粒子表面の粒子がはがれやすく、トナーの転写性が変化しやすいことを示す。本発明のトナー粒子は、このRSm2/RSm1が、1.20以下であることが好ましく、1.10以下であることがより好ましい。RSm2/RSm1が、1.20以下であることにより、トナー粒子表面への付着力が小さい粒子の割合が少なく、耐久を通した転写性の変化がさらに小さいトナーを提供することができる。また、RSm2/RSm1が、1.10以下であることにより、トナー粒子表面への付着力が小さい粒子の割合を10%以下とさらに少なくすることができ、転写性の変化が小さくなるだけでなく、広範な環境下や厳しい使用条件下においても、優れた耐久性を有するトナーを得ることができる。RSm2/RSm1は、有機ケイ素重合体形成時におけるトナー粒子の製造方法、有機ケイ素重合体形成時の加水分解、重合時の反応温度、反応時間、反応溶媒及びpH等を調整することによって、前記範囲に制御することができる。また、有機ケイ素重合体の含有量によっても制御することができる。さらに、トナー粒子表面に凹凸を形成させる工程における、前記有機ケイ素重合体と凹凸形成用微粒子の添加タイミング等を調整することによっても制御可能である。 Normally, the value of RSm2, which is a state in which some particles on the toner surface are removed, is larger than RSm1. As RSm2 / RSm1 is larger, particles on the surface of the toner particles are more easily peeled off, and the toner transferability is more likely to change. The toner particles of the present invention preferably have an RSm2 / RSm1 of 1.20 or less, more preferably 1.10 or less. RSM2 / RSm1 is, by 1.20 or less, the ratio of particles adhesion is less on the toner particle surfaces is small, it is possible to provide a toner smaller transfer of the change through the durability. Further, RSM2 / RSm1 is, by 1.10 or less, the ratio of particles adhesion is less on the toner particle surfaces can be further reduced to 10% or less, not only the transfer of the change is small In addition, a toner having excellent durability can be obtained even under a wide range of environments and severe use conditions. RSm2 / RSm1 is the above-mentioned range by adjusting the method for producing toner particles during the formation of the organosilicon polymer, the hydrolysis during the formation of the organosilicon polymer, the reaction temperature during the polymerization, the reaction time, the reaction solvent and the pH Can be controlled. It can also be controlled by the content of the organosilicon polymer. Further, it can be controlled by adjusting the addition timing of the organosilicon polymer and the fine particles for forming irregularities in the step of forming irregularities on the surface of the toner particles.
