Patent ID: 8831470

Claim:
An image-forming device comprising: a first roller; a second roller, the first roller and the second roller being arranged in a first direction, the first roller being disposed upstream of the second roller in the first direction; an endless belt spanned between the first roller and the second roller to be circularly moved in a traveling direction, the endless belt spanned between the first roller and the second roller forming a first straight plane and a second straight plane that extend in the first direction, the first straight plane moving in the first direction when the endless belt is circularly moved; a plurality of photosensitive members arranged in the first direction and facing the first straight plane to form an image on the endless belt, the plurality of photosensitive members including an upstream most photosensitive member disposed at the most upstream in the first direction among the plurality of photosensitive members, each photosensitive member having a rotational shaft extending in a second direction orthogonal to the first direction; a transfer member opposed to the first roller across the endless belt to transfer the image formed on the endless belt onto a recording medium; a fixing member configured to fix the image transferred onto the recording medium; a conveying path formed between the transfer member and the fixing member to convey the recording medium from the transfer member to the fixing member; and a cleaning unit comprising: a cleaning member opposed to the first straight plane upstream of the upstream most photosensitive member in the first direction to collect a residual toner remaining on the endless belt; and a treating member disposed upstream of the cleaning member in the first direction to treat the residual toner collected by the cleaning member, wherein the conveying path passes between the cleaning member and the treating member.
