    摘要： The content of processing of an input image signal varies depending upon the conditions of an apparatus. In view of the fact that this results in the variations of correlation between tone data and toner consumption, a coefficient by which an integration value of the tone data is defined according to the content of the signal processing. In an image forming apparatus which performs tone correction as the signal processing and which has a characteristic (2) of forming images of higher densities relative to tone levels, for example, a larger amount of toner is consumed. Therefore, the coefficient of the apparatus is defined to be a higher value than that of an apparatus having a substantially linear characteristic (1). Conversely, in the case of an apparatus having a characteristic (3) of forming images of lower densities, thus consuming less toner, the coefficient is defined to be a lower value.

    摘要： A developing device according to the present invention comprises an image developing roll 4 having a roll surface treated with sand blast treatment to form a rough surface morphology in which aluminum anodizing is also applied to the surface of the image developing roll 4 where the rough surface morphology is formed. To the image developing roll 4 is applied a development bias consisting of a direct current voltage overlapped with an alternate current voltage. In this arrangement, the image developing roll 4 can perform the functions of conveying developer, charging developer, and preventing of discharge of the developing bias, while the image developing roll 4 can be manufactured from a metallic roll such as aluminum roll at a low cost. Moreover, a gradual scraping of the image developing roll 4 surface by external additives of toner 3 suppresses adhering of toner 3 onto the surface of the image developing roll 4, preventing the occurrence of filming.

    摘要： A developing device includes a supply member (3) disposed to rotate in contact with a developer carrier (4) to supply a developer layer having a predetermined thickness to the developer carrier surface. A layer forming member (2) is disposed to abut against the developer carrier to regulate the layer thickness of the developer so as to form a thin developer layer on the developer carrier. A bias application unit (5,6) applies an AC-superimposed bias voltage to the developer carrier. The AC-superimposed bias voltage is formed by superimposing an alternating current on a DC bias voltage. A latent image on a latent image carrier is developed with the thin developer layer formed on the developer carrier by the layer forming member. The bias application unit sets a maximum value of the AC-superimposed bias voltage lower than the charge potential of the latent image carrier, and sets the DC bias voltage lower than the middle between the charge and exposure potentials of the latent image carrier. The minimum value of the AC-superimposed bias voltage may be set lower than the exposure potential of the latent image carrier. The maximum and minimum values of the AC-superimposed bias voltage may be set so as to be identical in polarity with each other.
