Patent attributes
An image forming apparatus includes: an image bearing body on which surface a solid lubricant is supplied, forming and bearing an image on the surface; a charging member to which a voltage is applied, being in contact with the image bearing body to impart a charge; a voltage applying section that applies the voltage to the charging member, capable of switching the voltage between superimposed voltage on which DC voltage and AC voltage are superimposed and non-superimposed voltage including only DC voltage; an image forming section that forms a toner image; a transfer device that transfers the formed toner image to a transferring body; a cleaning member that contacts the image bearing body to scrape unnecessary substance from the surface; and a voltage switching section that switches the voltage applied to the charging member between the superimposed voltage and the non-superimposed voltage according to an amount of the solid lubricant.
