    Abstract: A developing roller includes a roller main body disposed to face, without contact, an outer circumferential surface of an image carrier. The roller main body includes a resin coat layer that is formed on an outer circumferential surface of a base body that is made of a metal including aluminum, the resin coat layer being made of a resin material and having electric conductivity. An AC impedance Z obtained from an application of an AC voltage at a frequency in a range from 0.05 Hz to 100 Hz is equal to or higher than 100Ω, and a phase angle θ satisfies a relationship of 0 rad

    Abstract: A toner conveying device includes a toner conveying portion having vertical and horizontal conveying portions, a conveying member arranged in the horizontal conveying portion, a toner loosening member, and first and second magnetic members. The toner loosening member is arranged in the vertical conveying portion to be movable vertically. The first magnetic member is attached to the bottom end of the toner loosening member. The second magnetic member is attached to a part of the conveying member facing the toner loosening member. The magnetic pole of the first magnetic member on its side facing the conveying member is the same as the magnetic pole of the second magnetic member on its side facing the toner loosening member. The toner loosening member vertically reciprocates as the repulsive magnetic field between the first and the second magnetic members changes periodically with the rotation of the conveying member.

    Abstract: A developing device includes a developing container including a first conveyance chamber and a second conveyance chamber disposed above the first conveyance chamber, a first stirring-conveyance member which conveys developer in the first conveyance chamber in a first direction, a second stirring-conveyance member which conveys the developer in the second conveyance chamber in a second direction opposite to the first direction, and a developer carrier. A second communication portion is formed which allows the first and second conveyance chambers to communicate with each other at their end portions on a downstream side in the second direction. In the first conveyance chamber, a guide member is disposed which guides, to the downstream side in the first direction, the developer passing through the second communication portion to fall into the first conveyance chamber.

    Abstract: A developing device includes a housing, a development roller, and a roller gear. The roller gear is disposed at one axial end of the development roller and transmits a rotational drive force to the development roller. The development roller includes a sleeve and a coating layer. The coating layer is formed by dipping the sleeve in a dipping bath with the sleeve directed axially vertically. The development roller is mounted to the housing such that a lower axial end of the development roller at the time of the dipping is an opposite axial end to the one axial end at which the roller gear is disposed.

    Abstract: A developing roller includes a roller main body disposed to face, without contact, an outer circumferential surface of an image carrier. In the roller main body, a boehmite layer has been formed on an outer circumferential surface of a base body that is made of a metal including aluminum, by a surface treatment by a boehmite method, and a resin coat layer has been formed on a surface of the boehmite layer, the resin coat layer being made of a resin material having electric conductivity.
