Abstract: A driving force transmitting apparatus includes first and second planetary gear units and switching and urging members. The first planetary gear unit includes a first mesh gear and a first locked gear provided with first locked portions. The second planetary gear unit includes a second locked gear provided with second locked portions, and a second mesh gear meshing with the first mesh gear. The switching member includes first and second locking portions and can move to (i) a first stop position at which the first locking portion stop the first locked gear, and, urged by the urging member, (ii) a second stop position at which the second locking portion stops the second locked gear. An interval between the second locked portions in a rotational direction of the second locked gear is larger than an interval between the first locked portions in a rotational direction of the first locked gear.

Abstract: A sheet discharge apparatus includes a main tray, a discharge unit, and an expansion tray. The main tray is pivotable between a closed position and open position relative to a sheet discharge apparatus main body. The discharge unit discharges the sheet onto the main tray in the closed position. The expansion tray expands a main tray stacking area and is movable between a storage position where the expansion tray is stored in the main tray and an expansion position where the expansion tray is slid from the storage position in a sheet discharge direction and expands the stacking area. At the expansion position, the expansion tray is pivotable independently of the main tray. A direction in which the expansion tray is pivoted upward is the same as a direction in which the main tray is pivoted from the closed to the opened position.

Abstract: A sheet conveyance apparatus includes a conveyance member, a drive source, a first member including a first ratchet portion, a second member including a second ratchet portion, and an urging portion. The first ratchet portion has a plurality of first transmission surfaces and a first guide surface. The second ratchet portion has a plurality of second transmission surfaces and a second guide surface. One of the first member and the second member is movable in the axial direction between an engaged position and a separated position. The number of times the holding surface allows the one of the first member and the second member to move from the separated position to the engaged position while the second member rotates once in the rotational direction with respect to the first member is smaller than the number of contact positions included in the plurality of contact positions during the drive transmission period.

Abstract: A transfer device can make more stable contact with a belt, thus yielding preferable transfer performance. In an image-forming apparatus in which the transfer device has a sheet member, the sheet member includes a conductive sheet, and an electrical connection path section (power source connecting section) for supplying voltage to the conductive sheet from the primary transfer power source, and the power source connecting section is arranged outside an image formation enabling region where a toner image can be formed on a photosensitive drum, in a direction perpendicular to the direction of movement of the intermediate transfer belt.
