PURPOSE:To miniaturize a device, to reduce the cost and to offer a user who uses only one developing mode with a device of good performance in terms of the cost by generating a high voltage output to a high voltage load according to the developing mode. CONSTITUTION:High voltage output generating circuits are disposed at the inside of a high voltage unit for negative film 51 and a high voltage unit for positive film 52. When the high voltage unit for negative film 51 is set to a reader/printer, the operation is controlled to perform negative development according to a control signal from a sequence control circuit 5 so as to perform positive development, the high voltage unit for positive film 52 is set instead of the unit 51. Consequently, a high voltage output corresponding to each developing mode can be generated to a high voltage load. Thus, the device can be miniaturized, and the cost can be reduced. Moreover, a user who uses only one developing mode enjoys high performance. |
