PURPOSE:To obtain a satisfactory recording picture on ordinary paper, by using one component magnetic toner which contains a magnetic substance having specific particle diameter, performing the development by forming a conductive path through a toner between the development sleeve and the sensitive body, and after that, performing its transcription. CONSTITUTION:As for the one component magnetic toner to be used, a magnetic substance whose mean particle diameter is 0.5-5mu is contained by 35-60wt%, and it is made to bond with resin whose specific resistance is 10<12>OMEGA.cm or more, so that the characteristic of a dynamic state at the time of development is remarkably different from the characteristics of a static state at the time of electrostatic transcription. In case when said toner is used, an electrostatic latent image is carried by performing the prescribed exposure to the sensitive body 2 to which negative charge has been equally provided, a toner adhering onto the development sleeve 6 which is rotating is made to contact, and development is made by injecting the charge of the opposite polarity from that of the latent image, through the toner chain 14. Subsequently, a toner image which has been formed on the sensitive body 2 is brought to suction transcription by performing the negative corona discharge from the reverse side of the transcription paper S to be fed. |
