PURPOSE:To control temperature rise in a device and overall power consumption as far as possible and make the device compact by heating only a section in which a latent image erasing means corresponds to a latent image formed previously under the non-presence of a contact material. CONSTITUTION:In the case an image is removed, consideration should be paid to the heating of a thermal head 22 at the time of forming a latent image to be synchronized with the heating for removing the image. The latent image is formed on a recording body belt 1 heated in liquid by the thermal head 22, and the recording body belt 1 is carried by a driving roller 71, developed, transferred and cleaned, and simultaneously the belt reaches an image removing means (ceramic heater 6). The heat-on time of the ceramic heater 6 is set in consideration of the relation between the distance from a latent image forming section and the feeding speed of the recording body belt so that sufficiently high temperature is developed when the latent image forming section reaches the position of the heater. It is preferable that the overall surface of a recording body is heated prior to the formation of latent image under the non-presence of a contact material and the image is removed. |
