Abstract
A developing device includes a developing container, a developer carrier, a seal member, and a pair of pressing members. The developing container has an opening. The seal member includes a contact end part, a first blocking part, and an interposed end part. Each of the pressing members has a pressing surface in which a cutout recess is formed. The developing container includes a second blocking part that is adjacent to each end part of the first blocking part in a rotary shaft direction and protrudes upward. The interposed end part is located at such a position as to overlap the cutout recess with respect to a circumferential direction, and the second blocking part is located at such a position as to overlap the cutout recess with respect to the rotary shaft direction.
