Abstract

PURPOSE:To prevent powder dusts from flying out from the hopper at a powder material supplement time, by covering the aperture part of the hopper main body for powder material supply of the dry copying machine with a plate-form elastic material and by providing a slit, to which the vessel for powder material supplement can be inserted, on this plate-form elastic material. CONSTITUTION:The aperture part for powder material supply of hopper main body 3 is covered with plate-form elastic material 8, and slit 7 to which vessel 5 for powder material supplement can be inserted is formed on this elastic material 8. For supply of powder material, aperture part 9 of vessel 5 is inserted from slit 7. At this time, slit 7 is deformed according to the form of vessel 5 by elasticity of elastic material 8, and powder material is supplied into main body 3. Consequently, powder material flying-out accompanied with drop is suppressed by elastic material 8, and powder material is prevented from being scatterred around the aperture for supplement.
