摘要： PROBLEM TO BE SOLVED: To prevent poor image density to be caused when residual toner is increased with time in a recess 42b of a developing roller 42, even though the developing roller 42 does not have a plating surface layer with lubricant fine particles embedded therein.SOLUTION: A developing device 4 includes: a supply roller 44 that supplies toner to a surface of a developing roller 42; a doctor blade 45 that regulates the amount of toner which is conveyed by an endlessly moving surface of the developing roller 42 to a developing position where a toner carrier faces a latent image carrier of an image forming device. In the developing device 4, a latent image is developed by depositing toner held in a recess 42b on the surface of the developing roller 42 onto the latent image of the photoreceptor 2 in a developing position α. In order to use the supply roller 44 as lubricant supply means for supplying lubricant to the surface of the developing roller 42, fixed lubricant is pressed against the supply roller 44.
