摘要 |
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. |
