Abstract
A developing device includes a developing roller that faces a drum , a supplying roller that supplies the toner to the developing roller , and a toner container for storing the toner. A toner layer forming roller contacts the developing roller and rotates in the same direction as the developing roller . A part of the toner is transferred from the developing roller to the peripheral surface of the toner layer forming roller to form a toner layer. The thickness of the toner layer on the toner layer forming roller is regulated by a blade . According to the rotation of the toner layer forming roller , the toner layer is carried outside the toner container , where the toner layer is transferred to the peripheral surface of the developing roller
