摘要： A photoconductive drum device for electrostatic copying machines or the like includes a temperature maintaining heater bent to a cylindrical form and accommodated in the main body of a photoconductive drum. The heater is constructed with a base plate and a heat generator attached to the base plate. The base plate has a parallelogrammatic form substantially corresponding to a shape which is obtained by cutting a hollow cylinder, having a diameter approximate to the inside diameter of the drum main body, along a helical cut line and unbending the cylinder.

摘要： An automatic document feeder, comprising a document supply section for supplying documents one by one toward a document platen, a belt feed section for transferring a supplied document to a predetermined position on the document platen to enable an image forming operation, and a document discharge section for discharging onto a document discharge tray a document fed from the belt feed section upon completion of the image forming operation, is attached so that it is upwardly turnable with respect to the document platen so as to enable manual and automatic document settings to be made selectively. Further, the automatic document feeder is designed to discriminate between manual and automatic document setting modes and to detect the presence or absence of a document at a predetermined position in the automatic document feeder when the automatic document setting mode is selected. The automatic document feeder is driven with a predetermined timing for the setting of documents.

摘要： In a gradation output adjusting method according to the present invention, a gradation correcting section 64 corrects a gradation value of input data in accordance with a predetermined gradation correcting curve and applies the data after the correction to a printer output section 66. In preparing a gradation correcting curve, test data for forming a gradation scale is inputted to the printer output section 66 from a CPU 70. An image corresponding to the test data is read by a scanner section 1. A proper gradation value to be applied to the printer output section 66 is found with respect to some gradation values of the input data on the basis of the result of the reading. A pre-gradation correcting curve is prepared on the basis of the proper gradation value. The pre-gradation correcting curve and a plurality of types of curve patterns previously stored in a ROM 72 are matched. A curve pattern which is best matched to the pre-gradation correcting curve is set as a detailed gradation correcting curve. Since the pre-gradation correcting curve and the curve pattern are matched to set the gradation correcting curve, therefore, the amount of operation may be small and processing time is reduced.

摘要： This invention relates to a color image forming apparatus which is capable of forming a mono-color image based on the color image input data. The apparatus includes a circuit for determining the highest value of the image input data. This circuit is called the highest value image data outputting circuit. The highest input color data value is found by comparing the values of the image data for the three primary colors (yellow, magenta and cyan) and outputting the value for the color having the highest input value. The apparatus further includes a mono-color image forming portion which forms a mono-colored image based on the output of the highest value image data outputting circuit.

摘要： The average value of each of yellow, magenta and cyan color image data of a color-to-be-converted which data are obtained at the time of pre-scanning of a copying machine and stored in memories, respectively, is calculated, and then, predetermined set values are respectively added to and subtracted from the calculated average values of yellow, magenta and cyan to obtain upper and lower limit values of the conversion range. When the lower limit value obtained by subtraction is below a predetermined lower limit restriction value, the lower limit restriction value is set as the lower limit value of the conversion range. With this feature, when an extremely pale color is specified as a color-to-be-converted in a region other than a background portion of a color original where no letters, etc. are printed, the color of the background portion is not converted together with the specified color.
