Abstract: PURPOSE:To improve accuracy in detecting the end of toner by forming mark patterns on parts provided on both sides of the printed area of a photosensitive drum or the part of the photosensitive drum which does not become the printed area before and after a printing action and detecting the mark pattern by a photosensor. CONSTITUTION:The photosensitive drum 7 is electrostatically charged by a primary electrostatic charger 8 and an electrostatic latent image is formed on the surface of the photosensitive drum 7 by transmitting printing information to an LED head 9 and projecting it to the photosensitive drum 7. At such a time, a mark signal for detecting the near end of the toner is transmitted to the LED head 9 every fixed period before and after the printing information, and the electrostatic latent image of the mark pattern is formed on the specified area of the photosensitive drum every fixed distance. Then, the photosensors 30a and 30b are provided to detect the toner image of the mark pattern, and the near end of the toner is detected. Thus, the end of the toner is detected with high accuracy.

Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To prevent acid burning by repickling a titanium (alloy) member in which colored spots are produced by pickling and substantially removing only an oxidized film on the surface while the dissolution of the titanium (alloy) base is suppressed. SOLUTION: A titanium (alloy) member in which colored spots are generated by pickling is immersed in an aq. soln. of 5 to 70 deg.C soln. temp. contg., by weight, 0.1 to 5% hydrofluoric acid and 0.5 to 30% nitric acid for 1 to 30sec and is repickled. In the case the content of acid exceeds the upper limit, titanium ions and titanium fluoride ions are excessively formed to regenerate acid burning. In the case the content of acid is made smaller than the upper limit value, it takes a long time for removing an oxidized film. As for another method, it is immersed in an aq. soln. of 5 to 100 deg.C soln. temp. contg. 0.1 to 80% sulfuric acid for 1 to 300sec and is repickled. Sulfuric acid has high capacity of dissolving the oxidized film of titanium.  In the case the content of acid exceeds the upper limit value, its oxidizability is made high, and the capacity of removing the oxidized film of titanium is deteriorated.
