摘要： A residual recording material amount detector for a laser printer of the present invention is provided with a continuous dot number detecting device for counting a number of continuous video signals for modulating a laser light source, a toner consumption data storage device for storing a toner consumption per number of continuous dots, and an integrated toner consumption storage device implemented by a nonvolatile memory for storing an integrated value of toner consumptions at the time of forming a series of dots calculated by the continuous dot number detecting device and the toner consumption data storage device. According to the residual recording material amount detector for the laser printer of the present invention, the toner consumption can be detected correctly irrespective of the kind of data to be printed.
