Compositions containing at least four kinds of amino acids selected from the group consisting of serine, aspartic acid, glutamic acid, glycine, alanine and proline as active ingredients are useful for improving joint function and skin function and have high safety and permit continued ingestion or administration.

Composition for improving joint function

In a toner supply control system for a printing device, a toner supply unit supplies a developing unit of the printing device with a two-component developer containing toner particles and carrier particles in accordance with a first control signal. A storage unit stores information concerning a plurality of toner marks formed on an electrostatic latent image carrying member of the printing device and developed by the developing unit. The toner marks respectively have patterns related to condition of the two-component developer. A selecting unit selects one of the toner marks in accordance with a second control signal. A sensor optically reads the toner mark formed on the electrostatic latent image carrying member and generates a detection signal. A first control unit generates the second control signal on the basis of the condition of the two-component developer. A second control unit generates the first control signal on the basis of the detection signal.

Toner supply control system and method

A two component developing apparatus includes a container (2a), a developing agent conveying means (20) for conveying a two component developing agent consisting of toner and carrier to an image carrier (1) from the container (2a), a mixing device (21, 22) for mixing the toner and the carrier in a toner storage section (28) of the container (2a), and a toner supplier (25) for supplying the toner in the toner storage (28) into the container (2a). The toner supplier (25) includes a toner supplying rollers (26, 27) which can vary a flow of toner per unit time and a controller (44) for controlling the supplying rollers (26, 27) on the basis of the detected flow of toner. The flow of toner per unit time at the supplying rollers (26, 27) is controlled on the basis of a consumption rate of toner. The toner supplying rollers may have cells or holes on their surface.
