Abstract
A developing device includes a casing having an opening extending in a first direction, a developing roller, a thickness-regulation member, an engagement portion and a sealing member. The thickness-regulation member includes a thin-plate member and a regulating portion. The thin-plate member is fixed to the casing and has a lateral end extending in a second direction. The regulating portion is fixed on the thin-plate member and has an end face extending in a direction. The engagement portion is fixed on the thin-plate member and positioned closer to the lateral end than the end face to the lateral end to provide a groove between the engagement portion and the end face. The sealing member is fitted in the groove and has a length in the first direction longer than a length of the groove prior to assembly of the sealing member into the groove.
