Abstract: A transfer unit includes a transfer roller, a guide, a holder and a lever. The transfer roller is configured to be pressed against an image carrier to form a transferring nip and to transfer a toner image from the image carrier to a sheet at the transferring nip. The guide is configured to guide the sheet to the transferring nip. The holder is configured to support a rotating shaft of the transfer roller in a rotatable manner and to support the guide. The lever is configured to support the holder in a turnable manner around the rotating shaft so as to press the transfer roller against the image carrier. The guide has an engaged part. The lever has an engagement part which is engaged with the engaged part. An engagement of the engagement part with the engaged part prevents a turning of the guide with respect to the lever.

Abstract: An image forming apparatus includes an apparatus body, an outer cover, a conveyance unit, a movable roller, and an interlock mechanism. The outer cover is provided turnably between an outer closing position forming one surface of the apparatus body and an outer opening position in which the one surface of the apparatus body is set openable. The conveyance unit is provided turnably between an inner closing position in which an inside of the apparatus body is set closable and an inner opening position in which the inside of the apparatus body is set openable. The movable roller is pressed by a fixed roller pivotally supported inside of the apparatus body when the conveyance unit is displaced to the inner closing position. The interlock mechanism interlocks an operation of opening the outer cover with an operation of opening the conveyance unit.

Abstract: An image forming apparatus includes an apparatus main body, a sheet feeding cassette, an image forming section, a delivery member, a conveying member, a lift plate, a driving section, a first switching section, a second switching section, and a driving control section. The conveying member is disposed in the reverse conveying path. The lift plate is enabled to change a position thereof between a sheet feeding position and a retracting position. The first switching section transmits the driving force to the delivery member and the conveying member. The second switching section transmits the driving force to the lift plate. The driving control section controls the first switching section, with the lift plate being placed in the sheet feeding position, to rotate the delivery member, and when the sheet is conveyed through the reverse conveying path, moves the lift plate from the sheet feeding position to the retracting position.

Abstract: An image forming apparatus includes a cover member, an opening/closing detecting device and an elastic member. The cover member is supported so as to open and close an opening formed in an apparatus main body. The opening/closing detecting device is configured to be switched into OFF state to detect that the cover member is in opening state where the opening is opened and into ON state to detect that the cover member is in closing state where the opening is closed. The elastic member is interposed between the opening/closing detecting device and the cover member. The elastic member is configured to be deformed when the cover member closes the opening and then to switch the opening/closing detecting device from the OFF state into the ON state.
