摘要： An image forming apparatus capable of maintaining cleaning performance of a cleaning brush and downsizing the apparatus main body. Transfer residual toner accumulated on the cleaning brush is transferred onto a photoreceptor by an electrostatic force, hence the cleaning brush becomes clean and the cleaning performance thereof improves. Therefore, the photoreceptor and a charging roller can be cleaned well by the cleaning brush over a long period of time, and the photoreceptor can be charged well by the charging roller over a long period of time. Moreover, because the transfer residual toner that is transferred from the cleaning brush onto the photoreceptor is recovered by a developing device, it is not necessary to provide the apparatus main body with a toner recovery portion that is specially designed for recovering the transfer residual toner, hence the apparatus main body can be downsized.

摘要： An image forming apparatus includes: an image carrying member having a movable surface; a charging device including a rotatable charging member which is supplied with a voltage including a direct voltage superimposed with an alternating voltage, and which contacts and charges the image carrying member; an electrostatic latent image forming device for forming an electrostatic latent image on the image carrying member; and a development device for developing the electrostatic latent image. The frequency of the alternating voltage is lower in a non-image forming area than in an image forming area. In the non-image forming area, the image carrying member is charged to a surface potential having a waveform shape in accordance with the alternating voltage, and the potential difference between the surface potential and the voltage applied to the charging member generates an electric field which moves toner adhering to the charging member to the image carrying member.
