Abstract: A drying apparatus includes a conveying device, a heating device, a conveying rollers pair, a driving roller rotation detection part, a driven roller rotation detection part, and a control part. The conveying device conveys a medium in a conveyance direction. The heating device dries the ink of the medium under a high temperature environment. The conveying rollers pair is disposed on a downstream side of the heating device, and includes a driving roller and a driven roller. The driving roller rotation detection part detects a rotating of the driving roller. The driven roller rotation detection part detects a rotating of the driven roller. The control part stops the heating device when the rotating of the driving roller is detected by the driving roller rotation detection part and a rotation period obtained by a detection result of the driven roller rotation detection part is longer than a reference rotation period.

Abstract: A drying apparatus includes an endless conveying belt, a conveying plate, and a suction device. The endless conveying belt has a number of through-holes, and supports the medium and conveys the medium in a predetermined conveyance direction. The conveying plate has a number of through-holes and supports the conveying belt in contact with an inner circumferential surface of the conveying belt. The suction device sucks air through the through-holes of the conveying belt and the through-holes of the conveying plate to attract the medium to the conveying plate. The conveying plate is formed so as to be expandable and contractable in a direction parallel to the conveyance direction.

Abstract: A drying device according to the present disclosure includes a conveying device, an air blowing device, and an exhaust device. The conveying device conveys a medium on which an image is formed, along a predetermined conveyance direction. The air blowing device sends air toward the medium from above the medium conveyed by the conveying device to dry the medium. The exhaust device takes in air above the medium from both sides of the conveying device in a width direction perpendicular to the conveyance direction and exhausts the taken air to an outside.

Abstract: An image forming apparatus includes a housing, a container body, and an electrostatic capacitance sensor. The container body contains a liquid and is placed on a ground surface which is a part of the housing. The electrostatic capacitance sensor detects a change in capacitance between a side surface of the container body and the ground surface to determine a change in quantity of the liquid in the container body. The top surface of the container body is a part of the housing. The top surface and the ground surface are in electrically conductive state, a distance between the top surface and the electrostatic capacitance sensor is longer than a distance between the ground surface and the electrostatic capacitance sensor, or the top surface and the ground surface are electrically insulated, or the top surface is opened.

Abstract: A wipe unit of the present disclosure includes a wiper, a wiper carriage, a wiper fixing member and a recovery tray. The recovery tray is arranged below the wiper, and includes a tray surface that recovers the ink wiped off with the wiper. The tray surface is inclined with respect to a horizontal plane, and makes the recovered ink flow in a predetermined direction so as to collect the recovered ink. The wiping portion is formed with the wiper and the wiper fixing member, and the wiping portion includes an ink drop portion which drops the ink wiped off with the wiper to the tray surface. The ink drop portion is formed such that the length thereof in a width direction orthogonal to the wiping direction is reduced as the ink drop portion is extended downward.

Abstract: A developing device includes a developing roller, a housing, and a film member. A side opening provided in the housing communicates with a suction device at an end in a rotation axis direction of the developing roller. A downstream cover portion of the housing covers the developing roller from a downstream side in a rotation direction of the image carrying member. Concave portions of the downstream cover portion and a portion of a film member bonded to the downstream cover portion form ducts that communicate from openings facing the image carrying member to the side opening.
