Abstract: A cooling absorption tower for a CO2 recovery device, comprises: an outer shell; a cooling section for cooling a flue gas, the cooling section being disposed in the outer shell; and an absorbing section configured to cause CO2 in the flue gas cooled by the cooling section to be absorbed in an absorption solvent, the absorbing section being disposed in the outer shell and above the cooling section.

Abstract: An image forming apparatus includes an image forming device to form a toner image onto a recording medium by transferring the toner image directly or indirectly onto the recording medium, the image forming device including a developer to develop a latent image formed on an image carrier into the toner image; and a controller to control the image forming device. The controller determines whether a first estimated time period is greater than a first predetermined time period, the first estimated time period being a time period from a time when image formation of one page of the image completes to an estimated time when image formation of a subsequent page of the image will start; and stops operating the developer based on a determination indicating that the first estimated time period is greater than the first predetermined time period.

Abstract: An image forming apparatus includes a polygon mirror configured to scan a photosensitive element with a writing beam; a developing unit configured to develop a latent image formed by the writing beam on the photosensitive element to form a visualized image corresponding to image data; a transfer unit configured to transfer the visualized image onto an image recording medium; a conveying unit configured to convey the image recording medium to a transfer position; and a writing control unit configured to control a rotation speed of the polygon mirror and a writing clock frequency of the writing beam so that a sub-scanning direction scale factor of the visualized image transferred onto the image recording medium having the second thickness is matched to a sub-scanning direction scale factor of the visualized image transferred onto the image recording medium having the first thickness.
