    Abstract: To provide a toner which hardly causes toner leakage and which is excellent in thin line reproducibility. A toner comprising colored resin particles containing a binder resin, a colorant and a release agent, and an external additive, wherein an equivalent circular area diameter is 5.0 µm or more and 10.0 um or less, and a compactness obtained as a ratio of an equivalent circular area diameter to a maximum length (the equivalent circular area diameter/the maximum length) is 0.915 or more and 1.000 or less, both of which are measured by a flow particle image analyzer.

    Abstract: A toner pack (100) storing a toner is provided in which the toner comprises a first toner particle and a second toner particle, a portion formed by connecting a plurality of protrusions comprising silicon is present on the surface of the second toner particle, the content of the second toner particle relative to the first toner particle in the toner pack is within a specific range, the toner pack has a storage portion (101) and a discharge member, the discharge member has a receiving port (107a), a discharge port (102a), a fixing part (107) to which the storage portion is fixed, and an inclined surface (102g1, 102g2, 102g3) that causes the toner to move toward the discharge port, and the inclined surface that is the closest to the storage portion is at an angle of 45 degrees or more and less than 90 degrees.

    Abstract: An electrostatic charge image developing toner set contains a white toner that contains white toner particles including a binder resin, a white colorant, and a release agent, and a non-white color toner that contains color toner particles including a binder resin, a color colorant, and a release agent, in which, in observation of cross sections of the white toner particles and the color toner particles, in a case where a proportion of an area of a domain of a release agent present in a surface layer region from a surface of the white toner particles to a depth of 1 µm or less with respect to an area of all domains of the release agent present in a cross section of the white toner particles is represented by Ww, and a case where a proportion of an area of a domain of a release agent present in a surface layer region from a surface of the color toner particles to a depth of 1 µm or less with respect to an area of all domains of the release agent present in a cross section of the color toner particles is represented by W C , a relationship of W C W is satisfied.
