PURPOSE:To obtain an excellent transferred image with a simple constitution by detecting the temperature of developer in contact with a photosensitive body and adjusting the forming circumstance of the transferred image based on the detected temperature. CONSTITUTION:The title machine is the one which utilizes that the temperature of the developer is nearly coincident with the temperature of the surface of the photosensitive body by the contact with the photosensitive body to adjust the image based on the temperature of the developer, and it detects the temperature of the developer 20 with a temperature sensor 25 providing in the suction port 24 of a pump 17. And the impressed voltage Ve of a halogen lamp 71 is corrected according to the temperature Te of the developer 20 under the control of a CPU. Namely, indication such as 'to read data of developer temperature', 'to obtain the section of temperature Tn', 'to obtain a reference voltage Ves according to the section of temperature Tn', 'to execute correction in accordance with an exposure scale to the reference voltage Ves' and 'to transmit a correction value as control data Dv' based on the output from the temperature sensor 25 is transmitted to a regulator 72. Then, the image can be adjusted according to the temperature of a drum with a simple constitution. |
