Image forming apparatus

摘要

An image forming apparatus includes a developing device; a temperature detecting unit measuring a temperature of a main body; a cooling unit cooling the inside of the image forming apparatus; and a controller controlling the cooling unit based on result of the temperature detecting unit. The controller increases an air flow rate of the cooling unit such that the air flow rate is higher than a predetermined rate if the result of the temperature detecting unit is higher than a first temperature during non image forming and the controller increases an air flow rate of the cooling unit such that the air flow rate is higher than the predetermined rate if the result of the temperature detecting unit is higher than a second temperature which is higher than the first temperature during an image forming operation.

1. An image forming apparatus, comprising:
an image bearing member; a developing device configured to develop with toner an electrostatic latent image formed on the image bearing member; a first temperature detecting unit configured to detect temperature; a second temperature detecting unit configured to detect temperature; a cooling unit configured to cool the inside of the image forming apparatus by blowing; and a controller which controls an operation of the cooling unit based on temperature information obtained from a detection result of the first temperature detecting unit and a detection result of the second temperature detecting unit, wherein the controller changes the flowing amount of the cooling unit from a first flowing amount to a second flowing amount when the temperature information reaches a first temperature level before starting an image forming job to form an image on a recording medium, and wherein the controller maintains a condition of the cooling unit just before starting the image forming job until the temperature information reaches a second temperature level which is higher than the first temperature level, and in a status in which the cooling unit is being driven at the first flowing amount, when the temperature information reaches the second temperature level, the controller changes the flowing amount of the cooling unit to the second flowing amount from the first flowing amount.
