1. A toner housing container, comprising:
a container body mountable on a toner conveying device and housing a toner to be supplied into the toner conveying device; a conveying portion provided in the container body and configured to convey the toner from one end of the container body in a longer direction thereof to the other end thereof at which a container opening portion is provided; a pipe receiving port provided at the container opening portion and capable of receiving a conveying pipe fixed to the toner conveying device; and an uplifting portion configured to uplift the toner conveyed by the conveying portion from a lower side of the container body to an upper side thereof and move the toner toward a toner receiving port of the conveying pipe, wherein the container body comprises a protruding portion protruding into a container body interior side of the container opening portion toward the one end, wherein the uplifting portion comprises
an uplifting wall surface extending from an internal wall surface of the container body toward the protruding portion, anda curving portion curving so as to conform to the protruding portion, and wherein the curving portion and the protruding portion are disposed and configured such that 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, wherein a flow rate index of the toner measured by a powder rheometer and represented by the following formula (1) is in a range represented by the following formula (2),
Flow rate index=(total energy at a rotation speed of 10 mm/s)/(total energy at a rotation speed of 100 mm/s) (1)1.8≦flow rate index≦6.5 (2). |
