Image forming apparatus with application of an adjustable lubricant amount onto an image carrier

An image forming apparatus includes at least one image carrier (1, 1a, 1b, 1c, 1d) that carries an electrostatic latent image on a surface of the at least one image carrier (1, 1a, 1b, 1c, 1d), at least one developing device (4, 4a, 4b, 4c, 4d) that develops the electrostatic latent image with a developer including a toner to which a first lubricant is added to form a toner image on the surface of the at least one image carrier (1, 1a, 1b, 1c, 1d), a lubricant applying device (8, 8a, 8b, 8c, 8d) that applies a second lubricant (10, 10a, 10b, 10c, 10d) onto the surface of the at least one image carrier (1, 1a, 1b, 1c, 1d), a lubricant application amount adjusting device (20) that adjusts an amount of the second lubricant (10, 10a, 10b, 10c, 10d) to be applied onto the surface of the at least one image carrier (1, 1a, 1b, 1c, 1d), and a control device (30) that controls the lubricant application amount adjusting device (20) to adjust the amount of the second lubricant (10, 10a, 10b, 10c, 10d) to be applied onto the surface of the at least one image carrier (1, 1a, 1b, 1c, 1d) according to an area of the toner image formed on the surface of the at least one image carrier (1, 1a, 1b, 1c, 1d).
