    摘要: An image forming apparatus, including: an image bearing member on a surface of which an electrostatic latent image is formed; a developing device which contains a developer and which has a rotatable developer carrying member, which abuts against the surface of the image bearing member, and a storage device storing information on image formation history, the developing device being adapted to visualize the electrostatic latent image on the surface of the image bearing member as the developer carrying member carries the developer to the electrostatic latent image; a moving mechanism which moves the developing device to one of a first position where development is performed and a second position where development is not performed; and a control device which controls, based upon the information on image formation history stored in the storage device, an operation for giving a charge to the developer according to a lapsed time from a finish time of image formation, in a state in which the developing device is moved to the second position by the moving mechanism. In the image forming apparatus, a toner is charged sufficiently in the developing device, and image failure due to insufficiency in a charging amount of toner may be prevented, thereby capable of forming a high quality image.

    摘要: An image forming apparatus includes a rotatable image bearing member including an image bearing layer and a base member for supporting the image bearing layer; a charging member contactable to the image bearing member for electrically charging the image bearing member; a voltage applying device for applying an oscillating voltage to the charging member; a weighting material inside the base member; and an elastic material between the base member and the weighting material. The elastic material has a hardness not more than 70 degrees (JIS-A), a thickness of 1-5 mm and an outer diameter larger by 40-400 microns than an inner diameter of the base member before it is press-fitted into the base member.
