    • A developing device includes a housing containing toner having an opening at a side thereof, a developing roller supplying the toner supplied through the opening to a photoconductive drum, and a regulator contacting the outer circumference of the developing roller to regulate the amount of the toner supplied to the photoconductive drum. The housing also includes a lower frame having both side portions and a lower end portion respectively forming both edges and a lower edge of the opening in a lengthwise direction, and an upper frame welded and coupled to the lower frame and including a leading end portion forming an upper edge of the opening and a recess portion recessed from the leading end portion at both end portions of the leading end portion in the lengthwise direction. Both side portions of the lower frame includes a first surface contacting the recess portion to prevent the upper frame from being pushed toward the developing roller when the upper frame is welded and coupled to the lower frame.
    • 显影装置包括容纳调色剂的壳体,该调色剂在其一侧具有开口,将通过该开口供给的调色剂供给到感光鼓的显影辊以及与显影辊的外圆周接触以调节供给的调色剂量的调节器 到感光鼓。 所述壳体还包括下框架,所述下框架具有分别在所述长度方向上形成所述开口的两个边缘和下边缘的两个侧部和下端部,以及焊接并联接到所述下框架的上框架,并且包括形成 开口的上边缘和在前端部的长度方向的两端部从前端部凹陷的凹部。 下框架的两侧部包括接触凹部的第一表面,以防止当上框架被焊接并联接到下框架时,上框架被推向显影辊。
