    Abstract: An inkjet ink has a volume reduction rate ΔV calculated using formula (1) “ΔV=100×(V0−V22)/V0” of at least 25% and no greater than 45%. In the formula (1), V0 represents a first volume of a liquid droplet of the inkjet ink at landing, on a non-absorbent recording medium, of the inkjet ink dropped onto the non-absorbent recording medium. V22 represents a second volume of the liquid droplet when 22 seconds elapse from the landing of the liquid droplet on the non-absorbent recording medium.

    Abstract: In an initial recovery stage of untransferred toner, a conveying stirring screw is rotated at a high speed by using a second driving path. When the amount of collected untransferred toner increases and the rotating torque of the conveying stirring screw reaches a setting torque value of a second torque limiter, a driving path is switched to a first driving path, so that the conveying stirring screw is rotated at a low speed. When the amount of the collected untransferred toner further increases and the rotating torque of the conveying stirring screw reaches a setting torque value of a first torque limiter, the first driving path is also disconnected to block torque transfer to the conveying stirring screw.

    Abstract: A developer container is fitted in a first direction to an image forming apparatus for forming an image on a sheet. The developer container includes a main body and a protrusion. An inner space filled with a developer is formed in the man body. The protrusion protrudes outward from an outer wall of the main body. The protrusion includes a plurality of wall surface parts facing in a direction opposite to the first direction. An order in which the plurality of wall surface parts are arranged when viewed in the first direction is different from an order in which the plurality of wall surface parts are arranged when viewed in a second direction intersecting with the first direction. A plurality of wall parts are formed integrally to connect the plurality of wall surface parts through the plurality of wall parts.

    Abstract: A toner conveying device of the present disclosure includes a conveying screw, a toner conveying pipe, and a plurality of convex portions that are formed on an inner wall surface of the toner conveying pipe. The conveying screw has a rotary shaft and a conveying vane that is formed on an outer peripheral surface of the rotary shaft. The toner conveying pipe has a circular section, and the conveying screw is rotatably disposed inside the toner conveying pipe. Each of the convex portions is formed within an area defined by half the circumference along the inner wall surface of the toner conveying pipe and supports the conveying screw so that an axial center of the rotary shaft substantially coincides with a center axis of the toner conveying pipe.
