| 英文摘要 | PURPOSE:To suppress deterioration in picture quality due to deterioration of a photosensitive body by increasing the output of a semiconductor laser, and correcting and setting a set value when the total value of the quantity of recording stored in a nonvolatile memory attains to the set number of sheets. CONSTITUTION:A microcomputer 1 counts the total number of recording sheets stored in an EEPROM14 every time recording is performed. When the output of the semiconductor laser 2 attains to a set value, the microcomputer 1 reads the counted value of the number of recording sheets out of the EEPROM14 and when the counted value is smaller than the 1st set value, deterioration ion picture quality due to deterioration of the photosensitive body is within a permissible range, so processing is carried out while the output of the semiconductor laser 2 is held at the set value. When the counted value is smaller than the 2nd set value, the counted value of the internal counter is increased by a specific value to increase the base current of a transistor 12, and the output of the semiconductor laser 2 is increased to correct and set the set value, thereby suppressing the deterioration in picture quality due to the deterioration of the photosensitive body. |
