PROBLEM TO BE SOLVED: To prevent a charge defect of a body to be charged, as well as preventing an abnormal discharge by preventing a coarse section on a brush from being brought into contact with the body to be charged at the time of charging, in a electrostatic charging device provided with a magnetic brush charging member. SOLUTION: This electrostatic charging device provided with a magnetic particles carrier 2A being a charging member disposed rotationally, and a means 25 applying voltage to the magnetic particles carrier 2A, is composed so as to make the body to be charged 1 charged by letting the magnetic particles 23 stuck/held as the magnetic brush B in binding them with the magnetic force, and moreover the magnetic brush B held in contact with the charged body 1 by applying the voltage on the magnetic particles carrier 2A. In this case, the device is let the magnetic particles carrier 2A rotated before starting the charge on the charged body 1, the magnetic particles carrier 2A fixed during the charge of the charge on the charged body 1, and the position starting charge of the charged body 1 onward the charge nip width is made to be the charge area, and moreover the dense section on the magnetic brush B so as to come into contact with the charged body 1.
