Image forming apparatus with residual toner conveyance feature for improved detection/collection of accumulated residual toner

An image forming apparatus, comprising:

• an image bearing member which bears a toner image, said image bearing member being movable in a moving direction;
• a transfer member which transfers the toner image on the said image bearing member to a record member;
• a cleaning member that cleans toner adhered onto said transfer member;
• a toner container which contains toner cleaned by said cleaning member;
• a conveyance member which conveys the toner contained in said toner container;
• and
• a toner sensor which detects toner at a detection position in said toner container, wherein the detection position is positioned at a center area of said toner container in a direction orthogonal to the moving direction of said image bearing member;
• wherein the image forming apparatus is operable in a frameless print mode to form a toner image in a second area on said image bearing member and to transfer the toner image to edges of the record member, the second area including a whole of a first area corresponding to the record member on which the toner image is formed and being broader than the first area,
• wherein said conveyance member includes first screws to convey toner to a position corresponding to an area in which the first area is excluded from the second area in a direction toward the detection position, and second screws to convey toner to a position between said first screws and the detection position in a direction opposite to the direction toward the detection position,
• wherein said conveyance member includes a second cleaning member that cleans the toner at the detection position, and
• wherein said second cleaning member rotates according to a rotation of said conveyance member.
