ELECTROSTATIC CARRYING DEVICE, ELECTROSTATIC CARRYING METHOD AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve electrostatic carrying efficiency and original contribution rate regardless of the electrified state of toner. SOLUTION: In an electrostatic carrying device, a carrying base 31 placed in the vicinity of a photoreceptor drum 1 and provided with a plurality of electrodes is provided. In the carrying substrate 31, a range 55 to carry out carrying of the toner and a range 56 to mainly carry out toner pumping exist and a common electrode plate 70 is installed to face the carrying base 31 in the range 55. To the common electrode plate 70, voltage which is the same polarity as the electrifying polarity of the toner is applied by a power source 72.
