    Abstract: An optical scanning device includes a housing that houses an optical system for generating a light ray for optical scanning, and has a dustproof glass for emitting the light ray to an outside, and a cleaning system that is assembled to the housing and cleans the dustproof glass. The cleaning system includes a cleaning member, and a holder that holds the cleaning member, and with the holder moved in a specified movement direction relative to the dustproof glass, the cleaning member cleans the dustproof glass. The cleaning member includes a cleaner member that is adapted to contact a surface of the dustproof glass, and a pressing member that has a pressing surface for pressing the cleaner member toward the dustproof glass and is formed of an elastic body. In the movement direction, a width of the cleaner member is wider than a width of the pressing surface.

    Abstract: Each of first and second glasses to be cleaned has a first edge and a second edge. A cleaning system has a cleaning member having a contact surface adapted to contact a surface of the glass, and first and second holders that hold the cleaning member. A drive system moves the holder so as to perform an outward cleaning moving from the first edge toward the second edge and a return cleaning returning from the second edge to the first edge. At a start position of the outward cleaning, the holder is stopped so that a portion of the contact surface of the cleaning member is positioned inside the first edge, and at a start position of the return cleaning, the holder is stopped so that a portion of the contact surface is positioned inside the second edge.

    Abstract: An image forming apparatus includes image forming unit, frame structure, a plurality of rotational shafts, a plurality of drive gears, resin drive housing, and high voltage substrate. The frame structure includes at least one metal side plate frame having inner side surface facing internal space that accommodates the aforementioned unit and outer side surface opposite the inner side surface. The plurality of drive gears each rotate about an axis of the rotational shaft. The drive housing includes supporting side surface that supports one end of the rotational shaft and cavity in which the plurality of drive gears is accommodated, and the drive housing is open at the other end of the rotational shaft. The drive housing includes substrate supporting portion that supports the high voltage substrate, and is attached to the side plate frame such that the opening is sealed by the inner side surface of the side plate frame.

    Abstract: An optical scanning device includes a housing, a transmissive member, a wire-shaped member, a driving portion, a cleaning holder, a cleaning member, a stopper, and a control portion. The control portion is capable of executing a cleaning mode including at least one of a forward travel operation of controlling the wire-shaped member to travel in a first direction so that the cleaning holder moves along the transmissive member and a backward travel operation of, after executing the forward travel operation, controlling the wire-shaped member to travel in a second direction so that the cleaning holder moves in an opposite direction to a direction of the forward travel operation. The control portion executes a load releasing operation of controlling the cleaning holder to move by a prescribed amount in an opposite direction to the direction of the forward travel operation or the direction of the backward travel operation.
