Abstract
Provided are a nozzle wiping sheet, a nozzle wiping unit, and an image forming apparatus capable of preventing occurrence of streaks during printing immediately after maintenance. A wiping member (120) wipes a nozzle surface (57K) of a jetting head (56K) provided with a nozzle through which liquid droplets are jetted, in which a shape of the liquid droplet added dropwise to the wiping member (120) after a cleaning liquid (108) is added to the wiping member (120) satisfies the following condition when an aspect ratio of the liquid droplet after 40 seconds after the addition of the cleaning liquid (108) is assumed to be R, and the R is 1.3 or more.
