<p>PROBLEM TO BE SOLVED: To provide a developing device including a brush roller, in which leakage of a developer can be prevented.SOLUTION: The developing device includes: a brush roller 91 including a roller body 91A and a fiber member 91C implanted on an outer peripheral surface of the roller body 91A; an enclosure 94 which supports the brush roller 91 so that the brush roller 91 is rotatable; rotating members 98 which are provided on both sides in an axial direction of the brush roller 91, of the fiber member 91C so as to be rotatable integrally with the brush roller 91; a blade 92 which is in contact with the brush roller 91 and the rotating members 98; and a first side seal 100 which is in contact with outer peripheral surfaces of the rotating members 98 and is disposed between the enclosure 94 and the rotating members 98. Each of the rotating members 98 has an outer periphery diameter larger than an outer periphery diameter of the roller body 91A and smaller than a diameter of the brush roller 91 including the fiber member 91C.</p> |
