ABSTRACT:
An image recording apparatus in which a constant current is supplied from a high voltage source to a charging unit to charge a photo-sensitive material, and the constant current is further supplied to a peeling unit to peel a printing sheet off the photo-sensitive material on which an image has been recorded is provided with a high voltage supply current stabilizing circuit which comprises; a first resistor for stabilizing a constant current supplied to the peeling unit, the first resistor being larger in resistance than the peeling unit; and a second resistor for stabilizing a constant current supplied to the charging unit when the resistance of the first resistor is larger than the resistance of the peeling unit, whereby a constant current is stably supplied to the peeling unit even when the resistance of the latter changes.
