Abstract: A conveyance device includes a housing, a formation member, and a detection section. The housing has a first conveyance path, a second conveyance path, and a first communication path. The first and second conveyance paths each are a conveyance path for conveying a developer. The first communication path allows a first end portion of the first conveyance path and a first end portion of the second conveyance path to be in communication with each other via a communication surface. The communication surface has a first region and a second region. The formation member forms the second region of the communication surface so that a height of the second region from a bottom portion of the first communication path is lower than a height of the first region from the bottom portion of the first communication path. The detection section detects the amount of the developer.

Abstract: A fixing device includes an endless fixing belt, a belt guide, and a frame member. The belt guide has a fastening portion, an arc portion, and a contact portion. The fastening portion is fastened to the frame member. The arc portion extends from the fastening portion while curving in an arc shape along the inner circumferential face of the fixing belt and has an elastic force acting outward in the radial direction. The contact portion extends from one end of the arc portion in the circumferential direction toward the frame member and has a counter-face facing the inner circumferential face of the arc portion. The frame member has a regulating portion that extends toward the belt guide to make surface contact with, so as to overlap, the counter-face of the contact portion.

Abstract: A fixing device includes a fixing member, a pressing member, a charger, and adjusting part. The fixing member heats toner images on media. The pressing member forms nips with the fixing member and presses the media. The charger uses a corona discharge that occurs in an electric field generated around a discharging electrode so as to charge the fixing member to a same polarity of toner in the toner images. The adjusting part increases a bias applied to the discharging electrode in accordance with increase of a cumulative number calculated by accumulating a number of the media on which the toner images are fixed or increase of a cumulative printing amount calculated by multiplying a printing rate that indicates a ratio of an area of the toner images to an area of the media by the cumulative number.

Abstract: A fixing device includes a fixing belt, a pressuring member, a nip forming member, a supporting member, a heating source, a heat conducting member, and a reflecting member. The pressuring member comes into pressure contact with the fixing belt to form a fixing nip. The nip forming member presses the fixing belt toward the pressuring member. The heat conducting member comes into contact with an inner circumference face of the fixing belt and absorbs a radiant heat emitted from the heating source. The reflecting member includes a reflecting part and a regulating part. The reflecting part reflects the radiant heat emitted to the supporting member toward the heat conducting member. The regulating part is unified with the reflecting part and comes into contact with the inner circumference face of the fixing belt to regulate looseness of the fixing belt.

Abstract: A fixing device includes a first fixing member, a second fixing member, a charging portion, and a control portion. The first fixing member makes contact with a toner image on a sheet conveyed along a conveying passage. The second fixing member forms a nip. The charging portion generates an application current. The control portion can perform an application mode, in which the application current is generated, and a standby mode, in which no application current is generated. The control portion performs the application mode during a first period after initial start-up until the passage of a predetermined period and performs the standby mode during a second period after the passage of the first period until the passage of a predetermined period.

Abstract: A fixing device includes a fixing member, a pressing member, a pressure adjustment part and a linkage part. The pressing member forms a pressing area with the fixing member. The pressure adjustment part moves one of the fixing member and the pressing member in a direction close to the other of the fixing member and the pressing member to increase a pressure of the pressing area and moves one of the fixing member and the pressing member in a direction away from the other of the fixing member and the pressing member to decrease the pressure of the pressing area. The linkage part transmits an operation to decrease the pressure of the pressing area to the fixing member and then moves the fixing member along an axial direction.

Abstract: A fixing device includes a fixing belt, a pressuring member, a heating source, a heat conducting member and a reflecting member. The fixing belt is arranged rotatably. The pressuring member is arranged outside the fixing belt and comes into pressure contact with the fixing belt to form a fixing nip. The heating source is arranged inside the fixing belt to emit radiant heat. The heat conducting member comes into contact with an inner circumference face of the fixing belt and absorbs the radiant heat emitted from the heating source. The reflecting member includes a reflecting part and a nip forming part. The reflecting part reflects the radiant heat emitted from the heating source toward the heat conducting member. The nip forming part is unified with the reflecting part and comes into contact with the inner circumference face of the fixing belt to press the fixing belt to the pressuring member.
