1. An image forming system that performs an identification operation for identifying a component causing a predetermined sound, the image forming system comprising:
an image forming unit configured to form an image on a recording material;
a plurality of drive units configured to drive the image forming unit;
a sound detection unit configured to detect operation sounds of the plurality of drive units; and
a control unit configured to implement a drive mode for operating at least one of the plurality of drive units and not operating other drive units, without forming an image on a recording material by the image forming unit,
wherein the control unit implements the drive mode when the value of a counter reaches a threshold value, the counter being incremented with each image formation on a recording material by the image forming unit,
wherein the identification operation identifies a component causing the predetermined sound based on the operation sounds detected by the sound detection unit during a period in which the drive mode is being implemented,
wherein the plurality of drive units includes a first and a second drive unit,
wherein, when the first drive unit operates with each image formation on a recording material by the image forming unit, the value of the first counter corresponding to the first drive unit is incremented, and
wherein, when the second drive unit operates with each image formation, the value of the second counter corresponding to the second drive unit is incremented.
