Abstract:
1. An image-forming apparatus comprising: an image-bearing member configured to bear a toner image; a transfer member contacting with the image-bearing member so as to transfer the toner image from the image bearing member to a recording material; first and second cleaning members contacting with the transfer member so as to remove toner from the transfer member; a collecting member contacting with the first and second cleaning members so as to collect toner from the first and second cleaning members; and a power supply configured to supply electric power to the collecting member, wherein a potential difference between the transfer member and the first cleaning member, the potential difference generated by applying a voltage to the collecting member from the power supply, causes the first cleaning member to collect the toner on the transfer member, and a potential difference between the transfer member and the second cleaning member, the potential difference generated by applying a voltage to the collecting member from the power supply, causes the second cleaning member to collect the toner on the transfer member.
