摘要： An image forming apparatus of the present invention includes a charging device including a charge roller formed with annular grooves at opposite end portions thereof and configured to charge an image carrier. Annular gap forming members each are fitted in the annular grooves for forming a gap between the charge roller and the image carrier. The gap forming members each have an area of 1.0×10−6 m2 to 3.0×10−6 m2 in a section containing the axis of the charge roller.

摘要： An image forming apparatus includes at least one image carrier that carries an electrostatic latent image on a surface of the image carrier. At least one developing device 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 image carrier. A lubricant applying device applies a second lubricant onto the surface of the image carrier. A lubricant application amount adjusting device adjusts an amount of the second lubricant to be applied onto the surface of the image carrier. And, a control device controls the lubricant application amount adjusting device to adjust the amount of the second lubricant to be applied onto the surface of the image carrier according to an area of the toner image formed on the surface of the image carrier.
