    • A developing device includes a casing having an opening extending in a first direction, a developing roller, a thickness-regulation portion, a sealing member and a contact portion. The thickness-regulation portion includes a thin-plate member and a regulating portion. The thin-plate member has a base end portion fixed to the casing and a free end portion to which the regulating portion is fixed. The thin-plate member has a lateral end extending in a second direction. The regulating portion has an end face extending in a direction. The sealing member is disposed on the thin-plate member and in intimate contact with the end face of the regulating portion. The contact portion is fixed on the thin-plate member at a position closer to the lateral end than the sealing member to the lateral end and made of a material whose hardness is higher than that of the sealing member.
    • 显影装置包括具有沿第一方向延伸的开口的壳体,显影辊,厚度调节部分,密封构件和接触部分。 厚度调节部分包括薄板构件和调节部分。 薄板构件具有固定到壳体的基端部和固定有限制部的自由端部。 薄板构件具有沿第二方向延伸的横向端。 调节部具有沿一个方向延伸的端面。 密封构件设置在薄板构件上并与调节部的端面紧密接触。 所述接触部分在与所述密封构件相比侧端更靠近侧端的位置固定在所述薄板构件上,并且由硬度高于所述密封构件的材料制成。
