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.

An ink jet recording head, includes a nozzle array of nozzle flow paths; ink ejection orifices communicating with the nozzle flow paths; heaters in the nozzle flow paths; and ink with which the head is filled. The ink contains a coloring material, an acetylene glycol-based surfactant, and water, the surfactant containing one or more kinds of an acetylene glycol or an ethylene oxide adduct thereof, an average addition number of moles of ethylene oxide of the whole surfactant being 3 to 7. The ink has a viscosity of 1.5 mPa·s to 3.0 mPa·s. The head is a line type head having an opening area of each ink ejection orifice of 100 μm2 to 350 μm2, a total number of nozzles of 1,200 or more, and a length of the nozzle array of 2 inches or more, and the head is driven at a frequency of 1 kHz to 10 kHz.

An image forming apparatus includes a moving portion that moves a printing medium, with the moving portion capable of being mounted to the image forming apparatus, an image forming portion that ejects ink droplets to the printing medium that is moved by the moving portion and forms an image thereon, and a reference portion mounted to the image forming apparatus. In addition, a positioning portion forces the moving portion, mounted to the image forming apparatus, to abut against the reference portion so that a distance between the moving portion and the image forming portion is a predetermined distance.

The present invention is to provide a processing unit which can move smoothly to accurate position in a proper posture. The processing unit is provided with a support mechanism that supports a processing unit 26 so as to allow the processing unit 26 to be moved to a sheet processing position (processing tray) 24. The support mechanism includes the processing unit 26 and first and second support portions 50 and 55 that support the processing unit 26. The first and second support portions 50 and 55 apply, to different positions (j and k) of the processing unit 26 which are spaced from each other, a support force Fa acting from below to above (in a direction opposite to a gravity acting direction) and a support force Fb acting from above to below (in a direction same as the gravity acting direction), respectively.
