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.

An image forming apparatus includes a rotatable drum; a developing device for developing a latent image formed on the drum into a developer image; and a cleaning blade for removing developer remaining on the drum after the developer image is transferred from the drum onto a developer image receiving member. After image formation, a predetermined amount of strain of the cleaning blade is released and the drum is subsequently rotated. The drum is subsequently rotated in a direction identical to a rotation direction of the drum during image formation.

An image forming apparatus includes a rotatable drum; a charging roller for electrically charging the drum; a developing device for developing a latent image formed on the drum into a developer image; a cleaning device for removing a developer remaining on the drum after transfer; and a control device. The cleaning device includes a cleaning blade contacting 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 after completing 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 image bearing member is stopped.

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.
