Claim Text:
1. An image forming apparatus, comprising: a plurality of image forming sections including a first image forming section and a second image forming section provided adjacent to the first image forming section on a downstream side of the image forming section in an image conveying direction, with the first image forming section including a first image bearing body, a first developing unit for developing a latent image formed on the first image bearing body, and a first cleaning unit that contacts with the first image bearing body to clean off the first image bearing body, and with the second image forming section including a second image bearing body and a second developing unit for developing a latent image formed on the second image bearing body; a first temperature sensor provided on the first developing unit; a second temperature sensor provided on the second developing unit at a position opposite to the first cleaning unit; a first cooling unit configured to send airflow to the first developing unit to cool the first developing unit; a second cooling unit configured to send airflow to the second developing unit to cool the second developing unit; and a control section configured to control the first cooling unit and the second cooling unit, wherein the control section is capable of performing each of (1) a first mode where image formation is executed using both the first image forming section and the second image forming section, and (2) a second mode where image formation is executed, in such a state that the first developing unit is suspended but the first image bearing body is driven, using an image forming section, and wherein in the first mode, the control section controls the first cooling unit based on an output of the first temperature sensor regardless of a temperature detected by the second temperature sensor, and in the second mode, the control section controls the first cooling unit based on an output of the second temperature sensor regardless of a temperature detected by the first temperature sensor.
