Abstract: A CRT panel developing apparatus includes a body; a panel fixing portion, which is placed in the upper portion of the body and is structured so as to ground the conduction layer of the panel; a developing gun, which sprays powder that has been coated with organic matter on to the panel fixed to the panel fixing portion; a supply line, which is a passageway for the powder and air to be supplied to the developing gun; an air supply apparatus and a powder supply apparatus which are connected to the supply line; a powder charging portion, which is formed on the supply line that charges the powder that passes through the supply line; a turbulent air line which supplies air to the powder charging portion; a power supply apparatus that supplies electrical power to the powder charging portion; an evaporation portion, where the organic matter evaporates; an evaporation air line which supplies air to the evaporation portion; an evaporated organic matter line, which connects the evaporation portion and the supply line;

Abstract: A multiple charged developing gun provides a multiple charged electrode portion comprising a body and a flow path that is formed in an inner portion of the body and through which powder flows; an entrance, which is formed on one side of the body, connected to the flow path, and in which the powder flows through a powder supply line by being connected to a powder supply apparatus; an exit that is formed on the other side of the body, which is connected to the flow path that becomes gradually narrow; a multiple charged electrode portion that is disposed in an inner portion the body, which is near to the exit; and a cable, which connects the multiple charged electrode portion to a power supply apparatus.
