A cleaning method for removing a recording ink from a surface of a recording material conveying belt of a recording apparatus. The method includes the steps of detecting a recording material jam; press contacting a cleaning member to a surface of the recording material conveying belt in response to the detected jam, thus removing from the belt surface an improper discharge of recording ink; and separating the cleaning member from the surface of the conveying belt after cleaning for a period of time. The period of time is determined based upon an amount of the recording ink discharged onto the conveying belt surface.
