More Information
Summary:The invention relates to an electrostatic image developing toner, an electrostatic image developer, a toner cartridge, a process cartridge, an image forming apparatus, and an image forming method. The electrostatic image developing toner has toner particles containing a binder resin, and the binder resin contains 90 mass% or more of an amorphous resin, and has a maximum peak Ma in a molecular weight range of 2500-8000 (inclusive) in a differential molecular weight distribution curve measured by GPC of THF-soluble components, a molecular weight distribution curve having a minimum value (Mm) in the range of more than 8000 and less than 280000 and a maximum peak (Mb) in the range of 280000 to 900000, inclusive, and the area ratio (A/B) of A to B is 5.5 to 10, inclusive, where A is the area of a differential molecular weight distribution curve for a molecular weight of 100 to less than Mm, and B is the area of a differential molecular weight distribution curve for a molecular weight of Mm to 100000000, inclusive.
