Summary:The invention relates to a powder conveying device and an image forming apparatus which are not easy to cause poor conveying of powder. A first conveyance path (91) in which a first conveyance screw (71) (first conveyance member) for conveying toner (powder) in a substantially horizontal direction is built, a falling path (93) in which toner flowing out from an outlet (91b) of the first conveyance path (91) falls, and a second conveyance path (92) in which a second conveyance screw (72) (second conveyance member) is built are provided. Toner falling on the falling path (93) flows in from an inflow port (92a) and is conveyed in a substantially horizontal direction. Then, when viewed in a cross-section orthogonal to the conveying direction in which the toner is conveyed, the cross-sectional area of the space inside the first conveying path (91) that is not occupied by the first conveying screw (71) is larger than the cross-sectional area of the space inside the second conveying path (92) that is not occupied by
