PURPOSE:To improve the durability of a toner conveying member by pressing a toner conveyance member against a driving roller by a flexible belt guide at a part except an opposition part facing an image carrier and projecting the toner conveyance member to the image carrier side from the driving roller at the opposition part facing the image carrier. CONSTITUTION:The flexible belt guide 12 is extended along the outer periphery of the toner conveyance member 10 except the opposition part facing the image carrier 2 at both axial end parts of the toner conveyance member 10 provided to the outer periphery of the driving roller 9. Then this belt guide 12 is only tensed to press the conveyance member 10 against the driving roller 9 at the part except the opposition part facing the image carrier 2 and the driving roller 9 is projected to the image carrier 2 at the opposition part facing the image carrier 2. Consequently, even if the driving roller 9 deflects or becomes eccentricity, the deflection or eccentricity is absorbed by the deflection of the flexible belt guide 13 and the toner conveyance member 10 is used stably for a long period. |
