PROBLEM TO BE SOLVED: To provide an image forming device realizing the prolongation of the life of a reusable sheet by using the sheet so that the frequency in use of both sides of the sheet may not be uneven. SOLUTION: In the case of forming an image on the reusable sheet, the number of times of using the sheet is detected for the respective front and back surfaces of the sheet (S1). Then, the number of times of using the front surface is compared with that of using the back surface. When the number of times of using the front surface is larger (S2: Yes), the back surface is decided as an image forming surface, and the sheet is reversed and serves image forming (S3). When the number of times of using the back surface is larger or the same between both surfaces (S2: No), the front surface is decided as the image forming surface, and the sheet serves image forming as it is (S4). Thus, the image is formed on the surface whose number of times of being used is smaller. |
