Title:
IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2019215505
Kind Code:
A
Abstract:
To reduce the likelihood of the occurrence of communication failure and an error in sensor output values from a plurality of toner concentration sensors, even when a communication line in the apparatus is provided along with an output line of the toner concentration sensors.SOLUTION: A sensor output line 25 transmits, to a processor 24, sensor output values from toner concentration sensors 15a to 15d that are provided on sensor substrates 21a to 21d and measure the concentration of toner in developing devices. A data communication line 26 is provided along with the sensor output line 25 for access to storage devices 22a to 22d provided on the sensor substrates 21a to 21d. When data communication is not executed with the data communication line 26 at a timing to read the sensor output values, the processor 24 selects and feeds the toner concentration sensors 15a to 15d one by one and reads their sensor output values, or otherwise stops feeding to all the toner concentration sensors 15a to 15d.SELECTED DRAWING: Figure 3
