PURPOSE: To apply lubricant on a photoreceptor by a lubricant applicator without making an electrophotographic device large in size and without increasing the cost. CONSTITUTION: A developing device 23 is provided with four black, blue, red and yellow developing devices 40 to 43, and by rotating the developing device 23, each developing roller installed on each color developing device 40 to 43 is successively positioned on a developing position A facing the photoreceptor 20. And the lubricant applicator 50 is installed between the yellow developing device 43 for last developing and the black developing device 40 for first developing. And in the case the lubricant is applied on the photoreceptor 20, the developing device 23 is rotated after ending the last developing by the yellow developing device 43, and the lubricant applicator 50 is positioned on the developing position A on the way of returning the black developing device 40 to a home position facing the developing position A. |
