PROBLEM TO BE SOLVED: To provide a printing device capable of exchanging a toner cartridge while avoiding a situation that a developing part stops forming a printed image to the utmost. SOLUTION: This printing device is equipped with a reserve tank 407 for storing toner supplied to the rotary developing part 406, a toner cartridge motor 414 driving a toner supply mechanism 410 for supplying the toner from a toner cartridge 402a in the case of judging that the toner stored in a reserve tank 415 is less than a specified amount, and a detection part 403b detecting the opening/closing of the door 403a of a cartridge housing part 403. In the case of detecting that the door 403a is opened when the developing part 406 forms the printed image, the motor 414 is stopped so that the motor 414 and the mechanism 410 can be separated. |
