Description of the Related Art Conventionally, for example, in a laser printer, the developer remaining on the photosensitive member after image transfer is removed by a cleaning member such as a cleaning blade or a cleaning brush, and the removed developer is removed as shown in FIG. The cleaning screw 1 collects at the one end side of the cleaning device 3 through the recovery passage 1a of the cleaning case 1, and is put into the case 5 of the developer recovery device 4 through the downward opening 1b of the cleaning case 1, and the case 5 has a vertical drop passage 5a. Through its own weight into the horizontal conveying path 5b, the driving force from the outside is transmitted to the gear 6 to rotate the conveying screw 7, and the rotation of the conveying screw 7 conveys through the conveying path 5b.
For example, it was collected in a collection tank or a development tank.

げることとなった。However, especially when the temperature and humidity are high, the developer passing through the drop path 5a adheres to the inner surface 5c of the case 5 at the lower part of the drop path 5a, and the particles agglomerate as shown in the first step a. As shown in step b and third step c, the deposits were gradually deposited, and the passage was gradually narrowed to prevent the recovery of the developer.

昭５８ー１０２２６９号公報参照）。Therefore, among the conventional ones, a weight is hung in the drop path 5a, the weight is moved by the rotation of the conveying screw 7, and the developer is dropped by applying it to the developer adhering to the inner surface 5c of the case. There is one that prevents the clogging of the developer in the drop path 5a by preventing the accumulation of the toner (see JP-A-58-102269).

（特開昭５６ー６６８８４号公報および特開昭６２ー４
０４８４号公報参照）。A coil-shaped elastic member is provided in the drop path 5a, and the elastic member is vibrated to drop the developer by hitting the developer adhering to the inner surface 5c of the case to prevent the developer from accumulating and to fall the path 5a. There are those which prevent the clogging of the developer in JP-A-56-66884 and JP-A-62.4-4.

（特開平５ー２００７４号公報参照）。A plate-shaped elastic member is provided in the drop path 5a, and the elastic force of the elastic member strikes the inner surface 5c of the case to drop the developer adhering to the inner surface 5c to prevent the developer from accumulating and to drop the drop path. There is one that prevents the clogging of the developer at 5a (see Japanese Patent Laid-Open No. 5-00744).

However, even if the elastic member is vibrated and the inner surface 5c of the case is hit with the elastic member, the aggregated developer cannot be removed, and there is a problem that the developer is clogged.
