Abstract
Residual toner carried on the imaging surface of a photoconductive belt is removed by a cleaning sleeve, conveyed to a toner discharging station and let fall through an opening into a removable container. A spring biased closure member stops the opening when the container is removed for disposal, thereby preventing contamination to the adjacent structural elements. Means is provided for urging one to position the container always in a predetermined orientation relative to the opening at the toner discharging station. Undesirable particles entrained by the other surface of the belt is collected by a counter member which is located at the opposite side to the cleaning sleeve with respect to the belt. The counter member may take the form of a block of soft material or bristles carried on a support member.
