摘要： An image forming apparatus includes a plurality of process cartridges provided for black and for another color. The process cartridges each including a set of a latent image carrier, a charging unit that charges a surface of the latent image carrier, and a lubricant applying unit that applies lubricant to the surface of the latent image carrier. The process cartridges for black and for the another color each has a cartridge frame with which the process cartridge is attachable to and removable from an apparatus body. The cartridge frames of the process cartridges for black and for the another color being of the same type. The process cartridge for black differs from the process cartridge for the another color in the configuration of the charging unit. The amounts of lubricant applied by the lubricant applying units to the respective latent image carriers differ with respect to the configuration of the charging unit.
