摘要： The present invention provides a charging member, a charging device, an image forming apparatus, and a process cartridge that minimize local unevenness in potential of a charged object resulting from soiling of the charging member with soiling microparticles or soiling aggregates, that do not cause image failure such as unevenness in image density and scumming, and that output good images through the life of the charging member. The charging member charges a surface of the object by receiving a voltage while being in contact with the object, and satisfies the condition that Rzjis≦30 and Rsk≦0, where Rzjis represents the ten-point average roughness of a surface of the charging member in contact with the object and Rsk represents the skewness of a roughness curve.

摘要： An image forming apparatus includes a rotatable drum; a charging roller, contacting the drum, for electrically charging the drum; a developing device for developing a latent image formed on the drum into a developer image; and a cleaning device for removing a developer remaining on the drum after the developer image is transferred from the drum onto a developer image receiving member. The cleaning device includes a cleaning blade contacting the drum and having a fixed end and a free end which is located upstream of the fixed end with respect to a rotational direction of the drum. The image forming apparatus further includes a control device for controlling a rotating operation of the drum. The control device is capable of performing an operation for rotating the drum, in a direction identical to the rotational direction of the drum during image formation effected by rotating the drum, after a lapse, without next instruction of image formation, of a predetermined period from a stop of rotation of the drum once made after completion of the image formation. The predetermined period is longer with a larger number of sheets subjected to the image formation in an image forming job before the rotation of the drum is stopped.

摘要： An apparatus for fixedly securing a cylinder head cover to the cylinder head of an engine having a bolt embedded in and projecting outwardly of the engine so as to protrude through a hole in the cover. A cap nut is engaged with the outer end of the bolt for pressing the cover against the cylinder head. A seal packing and a washer are disposed in surrounding relationship to the bolt and confined between the cover and the cap nut. The seal packing includes an annular lip portion which projects axially of the seal packing and passes through a hole in the washer, which annular lip portion is disposed in snug sealing engagement with an end wall of the cap nut in surrounding relationship to the bolt. The washer preferably cooperates with at least two such bolts to prevent rotation of the washer.
