    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 developer conveying device includes a housing, a developer conveyance path and a conveying member. The developer conveyance path extends between the pair of wall portions of the housing. The conveying member conveys developer from one wall portion toward the other. The conveying member includes a spiral member, shaft portions, a rib member, a supporting member and a projecting portion. The spiral member is formed by connecting spiral pieces in a conveying direction of the developer and includes a hollow interior formed by the connected spiral pieces. The rib member extends in the conveying direction and bridges adjacent ones of the spiral pieces of the spiral member. The supporting member connects an end part of the rib member in the conveying direction and the shaft portion. The projecting portion projects from the end part of the rib member more toward the wall portion than the supporting member.

    Abstract: A fixing device includes a fixing member, a pressurizing member, a charging portion, and a control portion. The fixing member rotates while being heated. The pressurizing member forms a nip portion between itself and a surface of the fixing member in such a way as to hold a sheet therebetween and conveys the sheet by rotating together with the fixing member, wherein an image of toner has been formed on the sheet. The charging portion electrically charges the surface of the fixing member to a polarity that is same as a charging polarity of the toner by supplying a charging current to a pair of electrodes that is disposed to face the surface of the fixing member. The control portion derives an index value of a charge amount of the toner on the sheet, and adjusts the charging current based on the index value.

    Abstract: A developer conveyance device includes a housing and a conveyance member. The conveyance member is supported to the housing and rotates to convey developer. The conveyance member includes a shaft portion, a helical member, and a plurality of reinforcement members. The plurality of reinforcement members are disposed in a circumferential direction of rotation of the conveyance member. When viewing a cross section in a direction intersecting with the rotational axis, an outer circumferential surface of the helical member includes a facing region and a non-facing region, which are defined for one reinforcement member of the plurality of reinforcement members, the facing region being a region where the one reinforcement member of the plurality of reinforcement members is projected on an opposite side of an outer circumferential surface of the helical member through the rotational axis, and the non-facing region being a region of the outer circumferential surface of the helical member which is different from the facing region. The other reinforcement member of the plurality of reinforcement members is disposed in the non-facing region.
