Abstract
Abstract A copying apparatus capable of performing a first preset number of copying operations corresponding to a first original document in a successive copying operation mode, and performing a second preset number of copying operations corresponding to a second original document in an intruded copying operation mode includes preset number display elements for indicating a first and second preset numbers, first counter for counting a number of copying operations, a copy number display element for indicating a value counted by the first counting means, a second counter for counting a discharged copy paper after the completion of a copying operation, and a detector for detecting a jam of the copy paper. The counted value of the first counter is revised so as to be equal to the counted value of the second counter when a copy paper jam occurs.
