    Abstract: A cleaner is provided. The cleaner includes a cleaning blade having an edge to be contacted with a surface of a member to be cleaned while moving relative to the member to clean the surface of the member. The cleaning blade includes the edge, and first and second side surfaces, wherein the edge is disposed between the first and second side surfaces. When the cleaning blade is not contacted with the surface of the member to be cleaned, the first side surface is opposed to the surface of the member, and when the cleaning blade is contacted with the surface of the member, the edge, and the first and second side surfaces of the cleaning blade are contacted with the surface of the member.

    Abstract: An image forming apparatus includes a latent image bearer, an intermediate transferor, a primary transferor, a second transferor, and a cleaning blade. The latent image bearer has a surface onto which a lubricant comprising zinc stearate is supplied. The intermediate transferor has a surface onto which the toner image is transferred, the surface including an adhering region to which the lubricant from the latent image bearer adheres. The cleaning blade cleans the surface of the intermediate transferor including the adhering region, after the toner image is secondarily transferred. In a region outside at least a horizontal A4 sheet passing width on the intermediate transferor, a ratio of a peak area derived from zinc stearate to a peak area derived from the intermediate transferor in a difference spectrum between attenuated total reflection (ATR) infrared absorption spectrums of the intermediate transferor in an unused state and after use is 0.892 or less.

    Abstract: A powder conveying device includes an inflow portion, a discharge portion, and a conveying screw. Powder flows into the inflow portion from outside of the powder conveying device. The powder flows out from the discharge portion to the outside of the powder conveying device. The conveying screw includes a shaft and conveys the powder from the inflow portion to the discharge portion in a conveying direction. A surface portion of the shaft at at least one of an upstream end or a downstream end of the shaft in the conveying direction, in at least one of the inflow portion or the discharge portion has a lower friction with the powder than another surface portion of the shaft at a position other than the at least one of the upstream end or the downstream end.

    Abstract: An elastic blade includes a contact edge to contact a contact object, an edge region including the contact edge and having a thickness smaller than or equal to 0.50 mm, and a backup region different in material or property from the edge region. The backup region is adjacent to the edge region on a cross section perpendicular to a direction in which the contact edge extends. The elastic blade has a converted Martens hardness X (N/mm2) in a range of from 0.9 to 2.9. The converted Martens hardness is defined as: X = S A S A + S B × h A + S B S A + S B × h B where SA represents a cross-sectional area (mm2) of the edge region, SB represents a cross-sectional area (mm2) of the backup region, hA represents a Martens hardness (N/mm2) of the edge region, hB represents a Martens hardness (N/mm2) of the backup region, and t represents the thickness (mm) of the edge region including the contact edge.

    Abstract translation: 其中SA表示边缘区域的横截面面积（mm2），SB表示支撑区域的横截面面积（mm2），hA表示边缘区域的马氏体硬度（N / mm2），hB表示马氏体 备用区域的硬度（N / mm2），t表示包括接触边缘的边缘区域的厚度（mm）。
