The method of operating an image forming apparatus as claimed in claim 5, wherein, The step S1 further comprises the following steps: Step S101: introducing the sample, moving the filter detection unit (22) to the feeding station and locating it below the sample container (27), introducing the concentrated sample in the sample container (27) into the filter detection unit (22); Step S102: filtering the sample, the filter driving device (225) extracts the water of the concentrated sample on the filter layer (223) through the filter hole (224), so that the sample particles to be detected in the concentrated sample remain above the filter layer (223); Step S103: adding cleaning water, adding cleaning water into the filter detection unit (22) through the spray pipe (261) to form a water film, ensuring that the sample particles remain active.

7. The method of operating an image forming apparatus as claimed in claim 5, wherein, The step S3 further comprises the following steps: Step S301: moving the sample imaging unit, moving the sample imaging unit (23) above the filter detection unit (22) through the imaging positioning unit (25); Step S302: acquiring images, the sample imaging unit (23) takes a picture of the sample particles in the filter detection unit (22); Step S303: outputting data, the sample imaging unit (23) outputs image data to an industrial computer.
