IMAGE FORMING DEVICE

摘要: PROBLEM TO BE SOLVED: To provide an image forming device capable of improving working efficiency. SOLUTION: This comprises a weight sensor for measuring sheet storing parts 28, 29, and 30 including stored sheet, residue calculating means number residual sheets in the according to output from sensor, indicating calculated by means. The allows confirmation without requiring drawing pars before or previous residue. Thus, wasteful string is not required, operation can be continued generating lack as long supplied at adequate timing run-out so that efficiency improved.
