摘要： An apparatus for measuring the concentration of developer in a liquid printer, the apparatus includes a housing, a developer film forming device installed in the housing for forming a developer film, and a sensing device including a light source unit for emitting colored light corresponding to a range of wavelengths for which the light transmissivity is relatively low to a developer film of a selected color developer, and a photodetector installed corresponding to the light source unit and receiving the light emitted by the light source unit and transmitted through the developer film. Thus, a thin developer film is formed and the concentration of developer is measured by emitting light in a range of wavelengths for which the selected color developer has a relatively low light transmissivity to the developer film. The affect by the toner mixed with other color is relatively less and the concentration of developer can be measured close to the actual concentration although the developer is contaminated.

摘要： An image forming system of an electrophotographic printer. The system includes a photosensitive body on which an electrostatic latent image is formed, a developing unit which develops the electrostatic latent image with a developer, a transfer body onto which the developed image is transferred, a first image charging unit which charges the image so as to increase an electric adhesive force of the image transferred onto the transfer body, a second image charging unit which charges the image so as to reduce the electric adhesive force of the image transferred onto the transfer body in the rear of the first image charging unit, and a transfer unit which transfers the image passing through the first and second image charging units onto paper. When the image is transferred onto the transfer body, the first image charging unit increases the electric adhesive force of the image and prevents the image from dispersing, and the second image charging unit reduces the adhesive force suitable for transfer just before the image is transferred onto the paper, and thus the clear image can be maintained, and a transfer efficiency can be improved.
