Abstract: There is provided an image forming apparatus that can stably discharge liquid from a liquid discharge head and can be reduced in size by a simple structure. In an image forming apparatus, a gas compressor is provided so as to face the peripheral surface of an image forming drum , which corresponds to a range positioned outside a transport range in which a recording medium is transported and deviating from the transport range in a circumferential direction. The gas compressor is adapted to blow secondary compressed gas, which is generated by primary compressed gas supplied from the outside of the apparatus and of which the temperature is low, to the peripheral surface. The secondary compressed gas, which is blown from the gas compressor, is guided to the peripheral surface by a guide part and is diffused along the direction of a rotation axis of the image forming drum.

Abstract: A coating apparatus includes: a coating roller configured to apply coating liquid to a recording medium; a measuring roller configured to intermittently supply the coating liquid to the coating roller by being brought into contact with and being separated from the coating roller; a coating liquid pan configured to stores the coating liquid; and a roller cover configured to cover the measuring roller. When the measuring roller moves between a contact position where the coating roller and the measuring roller come into contact with each other and a separation position where the coating roller and the measuring roller are separated from each other, the measuring roller and the roller cover integrally operate while maintaining their relative positions, in a state where the coating liquid pan is fixed.

Abstract: A coating apparatus includes: a transport unit configured to transport an object to be coated; a coating liquid pan configured to store a coating liquid; a roller configured to be partially immersed in the coating liquid, rotate around an axis to draw up the coating liquid, and coat the coating liquid on the object; a support unit configured to detachably support the coating liquid pan and slidably supports the coating liquid pan; a positioning unit configured to position the coating liquid pan attached to the support unit at an attachment position; and a relative movement unit configured to relatively moves the support unit and the roller. When the support unit is located at an immersion position, a part of the roller is immersed in the coating liquid. When the support unit is located at a retraction position, the coating liquid pan is slidably supported without contact with the roller.
