Abstract
A toner pack stores a toner that has first and second toner particles. The surface of the second toner particle has a portion formed by connecting a plurality of silicon-containing protrusions on its surface, with the content of the second toner particle within a specific range relative to the content of the first toner particle. The toner pack has a storage portion and a discharge member, where the discharge member has a receiving port, a discharge port, a fixing part to which the storage portion is fixed, and an inclined surface that causes the toner to move toward the discharge port. 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.
