PROBLEM TO BE SOLVED: To form an image on which a high quality is maintained as a whole through a part up to a high concentration part from a low concentration part (a highlight area) by forming a visible image by powder having a shape which powder containing pigment gathers in islands shape on a support body, transferring this visible image on a recording medium, and fixing the visible image on the recording medium at transfer time. SOLUTION: An exposing process and a developing process adjust so that a visible image having a shape which powder toner gathers in islands shape is formed on a photoreceptor. When the powder toner is stuck at an area rate of 10% to the whole area of a basic unit so that a part to which the powder toner is stuck and a part to which it is not stuck repeat in a basic unit of a prescribed pitch, and when the number of the powder toner stuck to a basic unit of a support body or the photoreceptor is denoted by (m) and the number of the powder toner brought into close contact with a part to which the poweder toner of a basic unit on the photoreceptor is stuck is denoted by (n), in the case where (0.8<=n/m<=1.0) is satisfied, it is defined as a visible image having a shape of gathering in islands shape is formed. |
