<p>PROBLEM TO BE SOLVED: To reduce possibility that a developer is blown out from the gap of a developing device and a medium or the like is contaminated.SOLUTION: A developer holder 340 is a cylindrical member and supplies the developer to an image holder on which an electrostatic latent image is formed, while being rotated in a state of holding the developer. A container 341 stores the developer holder 340. A discharge path forming member 342 covers a part of the developer holder 340 along the outer peripheral surface of the developer holder 340 and forms a discharge path 343 for discharging air from the inside of the container 341 to the outside of the container 341 between the discharge path forming member 342 and the inner wall surface of the container 341. The discharge path forming member 342 covers a top part T being the highest position of a position through which the outer peripheral surface of the developer holder 340 passes and the discharge port 3432 of the discharge path 343 is provided in the position closer to the image holder than the top part T.</p> |
