ABSTRACT:
A toner scattering prevention device for preventing toner from scattering out of a developing device or a cleaning device. The device includes a toner sealing plate and a clamp arrangement. The clamp arrangement prevents the toner sealing plate from being displaced in a direction at right angles to a widthwise direction of a toner image support member but allows displacement of the toner sealing plate, resulting from expansion or shrinkage of the toner sealing plate in the widthwise direction of the toner image support member due to environmental changes, aging, etc.
