PURPOSE:To solve such problems as deformation due to attachment of a reverse polarity toner to the parts surrounding a developed image, height of a magnetic brush erected by forming toner chains, and low image density, by treating the developed image with the magnetic toner by an image-correcting means. CONSTITUTION:An electrostatic latent image formed on an Se photoreceptor 1 is developed with an insulating magnetic toner. The developed image has deformation of the border of the image due to reverse-polarity toner caused by friction of the toner particles themselves present in the toner brush, or the like, and magnetic toner chains. This image is treated by an image correcting means 8 having a rotary magnetic roller 8-2 in its inside by applying bias voltage reverse in polarity to the electrostatic latent image to a sleeve 8-1. The reverse-polarity toner attaches to the sleeve 8-1, and the chains are also broken by an alternating magnetic field. As the image-correcting means, besides said means, application AC corona voltage or vibration of the photoreceptor may be used. |
