Abstract: A surveillance camera is equipped with a capturing unit to capture a subject; an illumination unit that applies illumination light to the subject; a main body that is approximately formed in a cuboid that is long in a top-bottom direction and has an internal housing space that is partitioned by a partition plate into a lower space that houses the capturing unit and an upper space that houses the illumination unit; a visor that projects from a front surface of the main body so as to be inclined forward and covers a light-receiving space formed in front of the capturing unit; and a water repelling portion that is formed in step form in a tip portion of the visor.

Abstract: An inkjet-type image forming apparatus, includes: an intermediate transfer body that has an outmost surface layer and transfers a photo-curable ink to a recording medium; a light irradiator that performs a tentative-curing treatment by photo-curing the photo-curable ink after the ink is landed on the intermediate transfer body and before the landed ink is transferred to the recording medium; a temperature controller that causes the outmost surface layer to be melted, expanded, or contracted; and a transferor that transfers the photo-curable ink landed on the intermediate transfer body to the recording medium.

Abstract: A fixation apparatus includes an endless fixation belt, a pad portion, an opposing rotating body, a heat source, a tensioned support portion, a support portion, and an opposing portion. The tensioned support portion supports the fixation belt under tension. The support portion is arranged downstream from a fixation nip portion in a direction of rotation of the fixation belt, and supports the fixation belt from an inner circumferential side of the fixation belt. The opposing portion is arranged as being opposed to an outer circumferential surface of the fixation belt with a space being interposed. The support portion includes a contact area where the support portion and an inner circumferential surface of the fixation belt are in contact with each other. The opposing portion is arranged as being opposed to the contact area.

Abstract: An image forming apparatus includes: a drop applier that applies a drop to a surface of a coating layer formed on a surface of a recording medium; a viscosity improver that improves viscosity of the drop on the surface of the coating layer; and a roller that rolls the drop improved in viscosity, wherein the drop at a time of rolling has lower viscosity than the coating layer.

Abstract: A fixing device is for fixing a toner image on a recording medium an image forming apparatus. The fixing device includes a fixing belt, a heating member, a nip area member, a pressing member, and a protrusion. The fixing belt is held by the heating member and the nip area member. The pressing member presses the fixing belt against the nip area member while being rotationally driven. The toner image is fixed on the recording medium in a nip area where the pressing member presses the fixing belt against the nip area member. The protrusion is in contact with the inner surface of the fixing belt. In the fixing device, the fixing belt is in contact with small areas only other than the heating area and the nip area to reduce the heat loss.

Abstract: For each of N imaginary regions divided at predetermined intervals in the direction of the rotation shaft of a developer roller (12), the amount of toner consumed when an image is formed is previously calculated. Then, the same amount of toner as a toner consumption amount calculated for each imaginary region is supplied to a development device (2) earlier by a time in which the toner supplied from a toner hopper (5) is transported to each imaginary region than at the time of the development. Thus, it is possible to maintain a toner concentration within the development device within a predetermined range without the toner being dispersed and an image formation speed being reduced even if an image having a high print rate is formed.
