摘要： An object of the present invention is to provide an image forming apparatus and a method for forming an image that are capable of controlling the consumption of opposite polarity particles and suppressing the reduction of toner charge amount due to the carrier deterioration and can form high quality images over a long period of time even in the case where large quantities of images with small image area ratio are printed. The image forming device comprises a developer including the opposite polarity particles, a developer carrying member, a toner carrying member, and a voltage applying section for applying bias voltage overlapped with alternating current between the toner carrying member and the image carrying member, wherein the bias voltage overlapped with alternating current is a vibrating waveform including a trapezoidal wave, or a vibrating waveform in which a blank is inserted during application of a reverse development side voltage component.

摘要： A development apparatus and an image forming apparatus capable of minimizing deterioration of the carrier for a long time, even in the case of continuous formation of images of smaller image area ratio. The charging of toner is assisted by using the developer composed of a mixture of toner and the carrier, to the surface of which is added the reverse polarity particle having a polarity reverse to that of the charged toner. Separation of the toner or reverse polarity particle of the developer prior to the process of development prevents the reverse polarity particle from being consumed in the developing area, whereby the effect thereof is maintained for a long time.
