摘要： An image forming apparatus includes an image bearer, a rotation shaft, a developing device, and a supply portion. The developing device includes a developing device main portion that rotates around the rotation shaft between a developing position and a retracted position and includes a developer, a developer bearer to face or be away from the image bearer depending on whether the developing device main portion is at the developing position or the retracted position, a replenishment portion having a replenishment port with an opposite surface formed by an arc drawn around the rotation shaft to replenish the developer, and a non-rotating portion. The supply portion has a supply port with an opposite surface formed by an arc drawn around the rotation shaft and facing the opposite surface of the replenishment port. The supply port communicates the replenishment port and supplies the developer to the developing device through the replenishment port.

摘要： A sealing structure includes a housing to accommodate powder, a powder roller having a surface to bear and convey the powder, and an entrance seal disposed between the powder roller and the housing to allow powder remaining on a circumferential surface of the powder roller to enter the housing. A pair of left and right edge seals is provided in a circumferential direction of the powder roller to overlap with outer circumferential surfaces of both ends of the entrance seal, respectively. Both ends of the entrance seal include powder damming sections extended from both ends thereof along the pair of left and right edge seals, respectively. A pair of inner edges of the respective powder damming sections is each sandwiched between a corresponding one of the pair of left and right edge seals and the powder roller while substantially symmetrically inclining from the rotation direction of the powder roller.
