Abstract: An image forming apparatus includes an exposure unit, a developing unit, a transferer, a fixer, a determiner, a blower, and a controller. The exposure unit exposes an image bearing member to light according to image data to form an electrostatic latent image. The developing unit is configured to develop the electrostatic latent image into a toner image. The transferer transfers the toner image onto a recording medium. The fixer heat fixes the toner image to the recording medium. The determiner determines a state of at least one of a temperature and a humidity inside the image forming apparatus. The blower generates airflow inside the image forming apparatus. The controller reduces the airflow volume of the blower based on a determination result of the determiner as the degree of the occurrence of dew condensation increases.

Abstract: An image forming apparatus 100 includes a photosensitive drum 21 on which an electrostatic latent image is formed by being scanned with a light beam emitted from a light source 29 through a transparent member 26, a developing roller 23 that develops the electrostatic latent image formed on the photosensitive drum 21 to form an image on the photosensitive drum 21, a transfer roller 24 that transfers the image developed and formed by the developing roller 23 to a sheet S, a fixing portion 30 that heat-fixes the image transferred on the sheet S by the transfer roller 24 to the sheet S, and a condensation member 28 provided in an airflow path A from the fixing portion 30 to the transparent member 26, and condenses and collects vapor in the airflow.
