Abstract
A developing device includes a developing member that develops an electrostatic latent image on an image carrying member with developer; a housing that houses and supports the developing member and has an open part facing the image carrying member; a storage portion provided inside the housing and storing the developer; and a leakage suppressing member provided at an edge of the open part that is on a downstream side in a direction of rotation of the developing member, the leakage suppressing member suppressing leakage of the developer from the housing toward the image carrying member. The housing has an opening on the downstream side in the direction of rotation with respect to the leakage suppressing member and on an upstream side in the direction of rotation with respect to the storage portion, the opening being open from a side of the developing member toward the outside of the housing.
