图像形成方法
摘要：
本发明要解决的课题是提供一种图像形成方法，是具有润滑剂涂布部件的图像形成方法，即便长期使用时也抑制带电不均所致的图像缺陷的产生，其结果，能够长期形成高画质的图像。本发明的图像形成方法，其特征在于，是至少具有将通过使静电潜像载体的表面带电并进行曝光而形成的静电潜像利用调色剂进行显影化的工序和在该静电潜像载体的表面涂布润滑剂的工序的图像形成方法，上述调色剂至少含有调色剂母体粒子和外部添加剂微粒，该外部添加剂微粒含有二氧化硅·聚合物复合体微粒，该二氧化硅·聚合物复合体微粒的硅原子存在比率至少满足下述条件A。条件A：15.0atm％≤硅原子存在比率(Si/(C+O+Si))≤30.0atm％。
摘要（英）：

A process of forming an image includes the steps of: developing an electrostatic latent image with a toner, the latent image being formed through charge of the surface of an electrostatic latent image carrier and exposure of the surface to light; and applying a lubricant onto the surface of the electrostatic latent image carrier. The toner includes a toner matrix particle and an external additive nanoparticle. The external additive nanoparticle comprises a silica-polymer composite nanoparticle. A percentage of atomic silicon present on the surface of the silica-polymer composite nanoparticle satisfies Condition A expressed by Expression: 15.0 atm %≦percentage of atomic silicon ({Si/(C+O+Si)}×100)≦30.0 atm %. The percentage of atomic silicon is determined from total amounts of atomic carbon, oxygen, and silicon present on the topmost surface of the silica-polymer composite nanoparticle and within 3 nm inwards from the topmost surface.
