摘要:
An electrophotographic toner, which is useful in an image forming method in which a toner image, which is formed on a latent image bearing member, is transferred onto an intermediate transfer member and then the transferred toner image is transferred onto a receiving material, including toner particles including a binder resin and a colorant, and a particulate fluorine-containing material.

A carrier for electrophotographic developer, including a core material and a resin layer formed on the surface of the core material, wherein the resin layer has a plastic deformation degree not less than 0.5 &mgr;m and an elastic deformation degree not less than 0.5 &mgr;m. The resin layer is preferably prepared by crosslinking a mixture including an acrylic resin having a reactive hydroxyl group and at least one of a perfectly-alkylated melamine compound and a perfectly-alkylated guanamine compound.

摘要:
To provide a toner that can provide long-term removability and high-definition images with reduced image layer thickness and densely-packed toner particles, a developer capable of forming high-quality images using the toner, a toner container for containing the toner, a process cartridge using the toner, an image forming apparatus using the toner, and an image forming method using the toner. The toner of the present invention is a toner having a substantially spherical shape with irregularities on its surface and containing at least a binder resin and a colorant, wherein a surface factor SF-1 that represents the sphericity of toner particles is 105 to 180, a surface factor SF-2 that represents the degree of surface irregularities of the toner particles is correlated with the volume-average diameter of the toner particles, and the toner particles have an inorganic oxide particle-containing layer within 1 μm from their surfaces.
