摘要： An image forming apparatus includes an open/close member is provided to be movable to a main frame between an open position and a closed position. A sensitive image forming element is provided to be placed in an exposed condition when the open/close member is moved to the open position. A protection unit is provided to be movable to the sensitive image forming element between an active position and a retracted position, the protecting unit being moved to the active position when the open/close member is set at the open position, so that the protection unit protects the sensitive image forming element so as to prevent the sensitive image forming element from being erroneously touched, and the protection unit being moved to the retracted position when the open/close member is set at the closed position, so that the protection unit does not restrain an operation of the sensitive image forming element.

摘要： An image forming apparatus is provided, which forms a releasing agent absorption toner image on an in-between printed sides area of a moving surface of an image carrier in the duplex printing mode. When the in-between printed sides area of the moving surface enters a transfer position at which a toner image is transferred from the image carrier to a recording medium, the transferring operation of transferring the toner image from the image carrier to a recording medium is interrupted to keep the releasing agent absorption toner image on the in-between printed sides area of the moving surface of the image carrier.

摘要： An image forming apparatus includes an image bearer; a toner image forming device; an intermediate transferor; a primary transfer power source; a secondary transfer nip forming device; and a secondary transfer power source to output a secondary transfer bias. One of two peak values of the secondary transfer bias is a transfer peak value to provide a greater transfer-directional force to move toner from the intermediate transferor toward the recording medium in the secondary transfer nip. An absolute value of the transfer peak value is greater than an absolute value of the primary transfer bias.

摘要： A cleaning device includes a cleaner, a casing, and an exit seal. The cleaner is configured to remove toner from a cleaning target. The casing accommodates the cleaner. The exit seal is attached to the casing and has a free end contacting the cleaning target at a position downward from the cleaner in a direction of movement of the cleaning target and an attached end attached to the casing. A space is disposed between a surface of the cleaning target and an opposite face of the exit seal opposite the cleaning target. The space includes an opening at a lateral end of the exit seal. The exit seal contacts the cleaning target from a trailing direction of the exit seal and seals the opening at at least an attached end side of the exit seal.

摘要： An image forming apparatus includes an image carrier; a facing member facing the image carrier via a transfer position; a power supply to output a voltage between a first position on the image carrier side and a second position on the facing member side; a resistance detector to detect electrical resistance between the first position and the second position via the transfer position; and a controller to switch between a first transfer mode in which the power supply outputs a direct current voltage, and a second transfer mode in which the power supply outputs a superimposed voltage. When a toner image on the image carrier is transferred onto a recording medium at the transfer position, the controller selects either the first transfer mode or the second transfer mode. When the resistance detector detects the electrical resistance, the controller selects the first transfer mode.
