Abstract: A developer driving device and an image forming apparatus are provided. The developer driving device includes a photosensitive drum driving gear installed on a flange which resides at one end a photosensitive drum on a photosensitive drum axis, that rotates the photosensitive drum connected to a main motor of a main body frame; and an intermediary gear installed to be able to perform a no-load operation on the flange, that rotates a developing roller driving gear connected to a sub motor of the main body frame. The photosensitive drum driving gear and the intermediary gear are connected to different motors.

Abstract: A developer layer thickness regulating device for a developing unit improves the sealing effect of a developer by regulating a thickness of a developer layer formed on a developing roller. The device includes a blade having a blade body that is in resilient contact with the developing roller. A bent part is formed on the blade body and extends at a predetermined angle from a developing roller contact part that is in contact with the developing roller, and a recessed part formed on the bent part. A sealing member is in contact with the blade. The sealing member overlaps with the recessed part.

Abstract translation: 用于显影单元的显影剂层厚度调节装置通过调节形成在显影辊上的显影剂层的厚度来改善显影剂的密封效果。 该装置包括具有与显影辊弹性接触的刀片主体的刀片。 弯曲部分形成在叶片本体上并且从与显影辊接触的显影辊接触部分以预定角度延伸，以及形成在弯曲部分上的凹部。 密封件与刀片接触。 密封构件与凹部重叠。
