| 主权项 | 1. A cleaning device, comprising: a first blade to slidably contact with a surface of an image carrier to which a toner including an external additive adheres; a second blade to slidably contact with the surface of the image carrier and to be provided downstream of the first blade in a rotation direction of the image carrier; and a lubricant applying mechanism section to apply a lubricant to the surface of the image carrier, wherein hardness of the first blade is more than hardness of the second blade; the first blade slidably contacts with the surface of the image carrier from a counter direction of the rotation direction of the image carrier; the second blade slidably contacts with the surface of the image carrier from a trailing direction of the rotation direction of the image carrier; and the lubricant applying mechanism section is provided downstream of the first blade and upstream of the second blade in the rotation direction of the image carrier. | ||
