摘要： An image forming apparatus using a two-component developer including a toner and a carrier as a developer, and provided with a toner replenishing device for replenishing with the toner has remaining amount detecting means for detecting the remaining amount of toner in a toner container, and informing means for generating a signal indicative of a small remaining amount of toner when the remaining amount of toner in the toner container becomes equal to or less than a predetermined amount, and a limit value is made effective only in a state in which the signal indicative of a small remaining amount of toner is being outputted. Also, by the density of the developer in a developing container becoming smaller than a predetermined limit value, a state in which a developing device is not being replenished with the toner from the toner replenishing device is judged. The limit value has a plurality of standards, and a value is selected and used in conformity with the remaining amount of toner in the toner container.

摘要： An image forming apparatus includes a charge removing device for removing the residual charge on a photosensitive film. The light emitted from an optical source of the charge removing device is selected from the range between the wavelengths which correspond to half of the maximum absorbance in a light absorbance characteristic of the photosensitive film. Since carrier generation does not occur by the light emitted by the charge removing device, the charging ability and the charge retaining ability of the photosensitive film are improved, and the image quality is significantly improved.

摘要： An image forming apparatus includes a photosensitive drum, a charging roller, a transfer roller, and a toner charging brush, wherein the toner charging brush reciprocates in a longitudinal direction of the photosensitive drum. In the image forming apparatus, when a number of rotations per a unit time of the image bearing member is assumed to be “a” and a number of times of reciprocation per unit time of the toner charging brush is assumed to be “b” assuming that R=b/a, R is set to be in a range of 1/25≦R≦3. However, R=m/n (m and n are integers of 5 or less) is excluded. Consequently, generation of a periodic attachment pattern appearing on the photosensitive drum is eliminated.
