Abstract
A developing device includes a developer bearing body that rotates in a first direction, and a supply brush roller, out of contact with the body, that also rotates in the first direction. A brush contact member has a first contact portion in contact with bristles of the roller above a first horizontal plane passing through a rotational axis of the roller and upstream in the first rotational direction of the roller of a portion of the roller opposing the body. A thickness adjusting member has a second contact portion in contact with the body below a second horizontal plane passing through a rotational axis of the body and downstream in the first rotational direction of the body of the portion of the roller opposing the body. A first vertical plane passing through the first contact portion is closer to the axis of the roller than is a second vertical plane passing through the second contact portion.
