摘要： An image forming apparatus includes an image carrier, a toner-image forming unit, a transfer unit, a cleaner, a plurality of cylindrical transport path forming members, a falling transport path forming member, and a discharge port. The falling transport path forming member has through holes in a side wall thereof. A second end of each of the transport path forming members is inserted into a corresponding one of the through holes. The falling transport path forming member forms a falling transport path that causes toner ejected from an ejection port disposed in the second end to fall. The discharge port is disposed in a lower part of the falling transport path forming member to discharge the toner to a discharge destination. The second ends of the transport path forming members are disposed offset from each other in a horizontal direction on the side wall of the falling transport path forming member.

摘要： An image forming apparatus includes a photoconductor and a lubricant applicator. The photoconductor carries a toner image formed by developing an electrostatic latent image with a toner. The lubricant applicator applies a solid lubricant to a surface of the photoconductor, and includes a brush roller, a holder, a pressing member, and a protrusion. The holder holds the solid lubricant. The brush roller scrapes off the solid lubricant from the holder and applies the scraped solid lubricant to the surface of the photoconductor. The pressing member has an ellipse shape and presses the solid lubricant toward the brush roller via the holder. The protrusion is disposed on the holder and contacts an inner circumferential surface of the pressing member at two positions provided in both end portions of the pressing member in a direction of a minor axis of the ellipse formed by the pressing member to support the pressing member.
