PURPOSE:To develop directly information on a non-worked recording member such as usual paper, etc., and also to make a titled device small-sized by heating a magnetic toner carried by a magnetic toner carrying member, by a laser beam which scans basing on a picture signal. CONSTITUTION:A magnetic toner 1 is carried by being made to adhere to a carrying belt 2 by utilizing magnetic force by a magnetic toner supply machine 4. It is electrostatically charged by an electrifier 5 on its way and reaches a developing part 9a. On the other hand, a recording form 10 is sent to a carrying drum 9 from a carrying roll 11, and at the time point when the tip part of the form reaches the developing part 9a, scanning corresponding to recording information is executed from a laser head 8, and the magnetic toner 1 is heated. By this heat, magnetism of the magnetic toner 1 which reaches a curie temperature is reduced, the toner is transferred onto the recording form 10 in accordance with an electric field formed between the developing part 9a and an opposed electrode 6, and the development is executed. |
