    • An image forming apparatus includes an image forming unit, a sheet conveyor and a main body that houses the image forming unit and the sheet conveyor. An operating unit is mounted to a front cover that can move between a closed position to cover an anterior side of the main body and an open position to expose a part of the main body. A retention mechanism retains the front cover at the closed position. The retention mechanism has a lock and a release. The lock is supported by one of the apparatus main body and the front cover and is selectively engageable with and detachable from the other. The release releases engagement of the lock, and is installed posterior to the operating unit in a region facing a back surface as viewed from an opening and closing direction of the front cover.

    • An embodiment of a developing device may include a housing, magnetic developer, and a developer bearing member. In some embodiments, the developer bearing member may include a magnet member. The magnet member may allow the developer to remain in the housing. A developer regulating member may be positioned proximate the developer bearing member and have one or more cut portions. In some embodiments, the cut portions may be positioned at each end of the developer regulating member in a surface facing the developer bearing member. The developer regulating member may regulate an amount of the developer held on the developer bearing member. A magnetic sealing member may extend along an outer peripheral surface of the developer bearing member at each end and may be positioned proximate the cut portion. In some embodiments, a portion of the magnetic sealing member may be positioned within the cut portion.
    • 显影装置的一个实施例可以包括壳体,磁性显影剂和显影剂承载部件。 在一些实施例中,显影剂承载构件可以包括磁体构件。 磁体构件可以允许显影剂保留在壳体中。 显影剂调节构件可以定位在显影剂承载构件附近并且具有一个或多个切割部分。 在一些实施例中,切割部分可以位于显影剂调节构件的面向显影剂承载构件的表面的每个端部处。 显影剂调节构件可以调节保持在显影剂承载构件上的显影剂的量。 磁性密封构件可以在每个端部沿着显影剂承载构件的外周表面延伸并且可以定位成靠近切割部分。 在一些实施例中,磁性密封构件的一部分可以位于切割部分内。

    • The object is to provide an image forming apparatus in which the copy sheet can be transferred with stable velocity and high accuracy even if there is variation in diameter due to machining tolerance. A pair of roller for feeding copy sheet pinching the sheet between the rollers consists of a rigid roller and an elastic roller which is pressed against the rigid roller, and both the rollers are connected by means of a driving mechanism so that the peripheral velocity of both the rollers are essentially equal. The diameter of said elastic roller is determined in the range between the first diameter with which the peripheral velocity of said elastic roller at the depressed part depressed due to the pressing of the elastic roller against the rigid roller without the copy sheet between the rollers coincides with the peripheral velocity of said rigid roller and the second diameter with which the peripheral velocity of the rigid roller assumed to have a diameter increased by the thickness of the copy sheet (rigid roller with increase diameter) coincides with the peripheral velocity of the elastic roller at the depressed part depressed due to the pressing of the elastic roller against said rigid roller with increased diameter without the copy sheet between the rollers.
