摘要： PROBLEM TO BE SOLVED: To simplify processing and a circuit composition when image data are array-converted to a lattice control electrode when an image is to be formed on paper directly. SOLUTION: An information processing unit 1 transfers image data to the processing circuit of an image forming unit 2 through a data array-conversion section 105 when outputting image data reproduced by an image forming unit 2. The data array-conversion section 105 array-converts image data in accordance with the lattice array of the image data control electrode 19. Array- converted data are stored in one of RAM 1 to 4 of the data storage section 201, and prescribed voltage is supplied through the switch 20 of a voltage switching section 204 from a control electrode voltage power supply 33 to each lattice electrode of the control electrode 19 through the data processing section 203 from the data storage section 201.

摘要： PROBLEM TO BE SOLVED: To stably control toner by eliminating the adherence of the toner to a control electrode by providing an image forming control electrode provided at the developer carrier side as a developer control electrode and a developer adherence preventive electrode to be applied with the voltage of the same potential as that of the carrier. SOLUTION: When a conductive layer 14c is so formed as to cover an area larger than a conductive layer 14b and a negative voltage such as for example, the voltage of the same potential as that of a toner carrier roller 12 is applied to the roller 12, the negative voltage of the same potential as that of the layer 14c is applied, and hence an electric field of toner flying direction is not formed on the area formed only with the layer 14c. Accordingly, the toner flying except an opening 14d is prevented. When toner fly preventive voltage is applied to the layer 14b while a transfer sheet 17 is discharged from an image forming unit immediately after printing, unnecessary toner is not adhered from the roller 12 to the sheet 17, and further the contamination of toner control electrode 14 is prevented.
