Abstract: An image forming apparatus includes a feeder, a conveyance section, an image forming section, a light emitter, a light receiver, a measuring section, and a permeation depth calculator. The feeder feeds a sheet. The conveyance section conveys the sheet. The image forming section forms an image on the sheet conveyed by the conveyance section using an ink. The light emitter emits near-infrared light to the sheet with the image thereon. The light receiver receives reflected light of the near-infrared light. The reflected light has been reflected by the sheet with the image thereon. The measuring section measures a received light quantity of the reflected light. The permeation depth calculator calculates a permeation depth of the ink permeating the sheet based on the received light quantity.

Abstract: A cap member includes a cap portion and a support member. The cap portion has a bottom surface portion and a side surface portion. The support member supports the bottom surface portion of the cap member. The bottom surface portion is provided with a groove portion defined by a first rib projecting from an upper surface of the bottom surface portion. A lid member which covers the groove portion is provided on, and in close contact with. an upper end of the first rib. The groove portion and the lid member define an air passage through which air passes. One end portion of the air passage communicates with an inner space of the cap member, and the other end portion of the air passage communicates with an outside of the cap portion.

Abstract: A fixing device includes a fixing belt, a pressuring member, a heat source, a pressing member and a first heating stop device. The fixing belt is provided to be rotatable around a rotation axis. The pressuring member is configured to be rotatable and to come into pressure contact with the fixing belt so as to form a fixing nip. The heat source is arranged at an inner diameter side of the fixing belt, provided at a position displaced from the rotation axis and configured to heat the fixing belt. The pressing member is configured to press the fixing belt to a side of the pressuring member. The first heating stop device is configured to face an outer circumferential face of a closest part to the heat source of the fixing belt and to operate at a first operating temperature so as to stop the heat source from heating the fixing belt.

Abstract: A fixing device includes: a heat source, a heating member, a pressure member, a heat absorption unit, a holding member, and an end part supporting member. The heat source generates infrared rays. The heat absorption unit is formed on an inner circumferential surface of the heating member, absorbs radiation heat of the heat source, and opposes an outer circumferential part of the holding member with a gap. The holding member has a hollow and cylindrical shape, and arranged between the heat source and the inner circumferential surface of the heat member, permits transmission of infrared rays and has heat resistance. The end part supporting member supports the holding member at both axial end parts of the heating member. The outer circumferential part of the holding member, the inner circumferential surface of the heating member, and the end part supporting member form a sealing space sealing the heat absorption unit.

Abstract: A fixing device includes a pressure member, a heating member, a coil, a first magnetic core, a second magnetic core, a shielding portion, and a switching belt. The second magnetic core is disposed to extend in a width direction in a hollow portion formed by the loop of the coil, and formed in an arc shape with a protruding portion at a side facing the heating member. The shielding portion is formed of a non-magnetic material to shield a path of a magnetic flux generated by the coil between the second magnetic core and the heating member. The switching belt includes a surface where the shielding portion is disposed to face a non-paper passing region in the heating member, suspended to be rotatable between a roller and the protruding portion, and selectively arranged in one of a shielding position and a non-shielding position by rotation of the roller.
