Abstract
A developing device includes a developing roller, toner supplying roller, regulation blade, and casing. The developing roller faces an image carrier on which an electrostatic latent image is to be formed, and supplies toner to the image carrier. The toner supplying roller faces the developing roller, and supplies the toner to the developing roller. The regulation blade faces the toner supplying roller at predetermined distance. The casing houses the developing roller, toner supplying roller, and regulation blade. The casing includes a toner catching support member facing the developing roller or the toner supplying roller between the regulation blade and the image carrier. The developing device further includes a toner catching member, which is arranged along a longitudinal direction of the toner catching support member and catches toner that drops from the developing roller, and a vibration generating portion, which vibrates the toner catching member.
