Abstract: An image forming apparatus is provided. The image forming apparatus includes an image forming unit to form a developer image in a developer agent on a photosensitive member, an intermediate transfer member arranged in a position to face the photosensitive member, a primary transfer member to transfer the developer image from the photosensitive member to the intermediate transfer member, a secondary transfer member to transfer the developer image from the intermediate transfer member to the recording medium, a cleaning member to remove materials adhered onto the intermediate transfer member, a container to store the materials removed from the intermediate transfer member, an attachment section, to which the container is detachably attached, and a conveyer to convey the recording medium to pass through a position between the intermediate transfer member and the cleaning member.

Abstract: An endless belt circularly moves to convey a recording medium placed thereon in a conveying direction. A plurality of photosensitive bodies is juxtaposed in the conveying direction with confronting the endless belt. A plurality of process units supplies developer to the plurality of photosensitive bodies to form a developer image thereon, respectively. A first collecting member contacts the endless belt to collect the developer on the endless belt. A second collecting member is capable of collecting from the first collecting member the developer collected on the first collecting member. A control unit applies a bias between the first collecting member and the second collecting member to inhibit the developer collected on the first collecting member from being transferred to the second collecting member when the first collecting member rubs the endless belt with the toner collected on the first collecting member.

Abstract: A collection device including: an accommodation part configured to accommodate therein collected adhering substance; and a detection part configured to detect an amount of the adhering substance in the accommodation part and including, a moving member configured to move from a first position to a second position, the accommodation part being capable of accommodating therein the adhering substance when the moving member is arranged at the first position and being full of the adhering substance when the moving member is in the second position, and a restraining member configured to restrain the moving member from moving from the first position to the second position when the moving member is arranged at the first position, and restrain the moving member from moving from the second position to the first position when the moving member is arranged at the second position.

Abstract: An image forming apparatus including: an image carrier; a holding member that contacts with the image carrier and is configured to carry adhering substance received from the image carrier; a belt that contacts with the image carrier; a collection member that contacts with the belt and is configured to collect adhering substance adhered on the belt; and a control device configured to apply a bias to the collection member, detect an electric resistance of the collection member, and control the bias that is applied to the collection member based on the detected electric resistance of the collection member so that the electric resistance of the collection member is converged within a predetermined range, when a cleaning operation of collecting the adhering substance adhered on the holding member from the holding member to the collection member is not performed.

Abstract: An image forming apparatus is provided. The image forming apparatus includes an image carrier, a conveyance belt which conveys a recording sheet via a position opposing the image carrier, a belt cleaner which removes adhered matters on the conveyance belt, a driving unit which drives the image carrier and the conveyance belt, a bias applying unit which applies a cleaning bias to the belt cleaner, and a controller which controls the driving unit and the bias applying unit such that when the image carrier is driven at a first speed, the cleaning bias is applied to the belt cleaner, and when the image carrier is driven at a second speed slower than the first speed, the cleaning bias is not applied to the belt cleaner.
