Abstract: A suit-type cosmetic air massage device for providing air pressuring massage upon a human whole body. To provide air pressuring massage, suit-shaped parts are made to cover a human whole body, and can be separated into an upper suit-shaped part and a lower suit-shaped part. And plural air bags are symmetrically installed within the left and right side from the position corresponding to the hand region to the position corresponding to the shoulder regions of the upper suit-shaped part, and from the position corresponding to the feet parts to the waist part of the lower suit-shaped part. These air bags are divided into the first, second, third and fourth group, and each air bag in each group can be supplied with air simultaneously or independently in order from connecting with the intake/exhaust instrument by an intaking/exhausting hose.

Abstract: A plurality of developing devices or units are supported on a supporting member or turret which is rotatable to revolve the developing devices to move a desired developing device to a developing station where the developing operation is effected with the desired one of the developing devices. The developing devices are each provided with detecting elements for detecting the remaining amount of the developer or the concentration of the developer. The detecting elements are located at such a position that during the rotation of the supporting member the developer particles move with the rotation of the supporting member so that the detecting element is constantly cleaned by the moving developer.

Abstract: A color image forming apparatus wherein a plurality of developing devices or units are supported on a supporting member or turret which is rotatable to revolve the developing devices to move a desired one of the developing devices to a developing station where the developing operation is effected with the desired one of the developing devices so that a color image is formed. The presence, absence or the amount of the developer within the developing devices are detected. When the detection indicates that the toner is to be supplied into a developing device, the developing device is moved to a predetermined developer supplying position, and then is stopped so that the developing device is supplied with the developer at the developer supplying position.
