摘要： Toner housing container includes: container body housing a toner; conveying portion conveying the toner from longer direction one end of container body to its other end at which container opening portion is provided; pipe receiving port receiving a conveying pipe fixed to toner conveying device; and uplifting portion moving the toner toward toner receiving port of conveying pipe. Toner has molecular weight distribution having a peak in a range of 103 to 104, and has C/R of from 0.03 to 0.55 between peak height C attributed to crystalline polyester resin and R attributed to non-crystalline resin when measured by FT-IR after stored at 45° C. for 12 hours. Container body includes protruding portion protruding from container body interior side toward the one end. Uplifting portion includes uplifting wall surface extending from container body internal wall surface toward protruding portion. Protruding portion is present between uplifting wall surface and toner receiving port.
