摘要:
A toner housing container includes: a container body housing a toner; a conveying portion; a pipe receiving port; and an uplifting portion. Flow rate index of the toner measured by powder rheometer and represented by “flow rate index=(total energy at a rotation speed of 10 mm/s)/(total energy at a rotation speed of 100 mm/s)” is in a range of “1.8≦flow rate index≦6.5”. Container body includes protruding portion protruding from container body interior side of container opening portion toward one end of container body. Uplifting portion includes: uplifting wall surface extending from container body internal wall surface toward protruding portion; and curving portion curving to conform to protruding portion. When the toner housing container is mounted on the toner conveying device, the protruding portion is present between the curving portion and the toner receiving port of the conveying pipe being inserted.
摘要:
A toner, containing: toner base particles; and an external additive, the toner base particles each including a binder resin and a releasing agent, wherein the external additive includes non-spherical coalesced particles in each of which primary particles are coalesced together, and wherein the coalesced particles satisfy the following formula (1): Nx/1,000×100≦30% where Nx is a number of the primary particles present alone relative to 1,000 of the coalesced particles, as observed under a scanning electron microscope after stirring 0.5 g of the coalesced particles and 49.5 g of a carrier placed in a 50 mL bottle for 10 minutes by means of a mixing and stirring device at 67 Hz.
