    摘要： An image forming apparatus includes an image forming section, a density detecting device, and a controller. The controller varies density target values set in accordance with the conditions for image forming on a recording material by the image forming section on the basis of the change in the density characteristics of a plurality of pattern images detected by the density detecting device.

    摘要： A cleaning member includes a blade portion contacted to a member-to-be-cleaned with respect to a direction counter to a movement direction of the member-to-be-cleaned, and a flexible supporting member. The supporting member includes one end portion where the blade portion is provided, another end portion including a portion-to-be-fixed for being fixed at the fixing portion, and a bent portion between the one end portion and the other end portion in a side remote from a surface of the member-to-be-cleaned toward an outside with respect to a line connecting the portion-to-be-fixed and a contact portion where the blade portion is contacted to the member-to-be-cleaned. The portion-to-be-fixed is provided downstream of the contact portion with respect to the movement direction of the member-to-be-cleaned. The blade portion is supported by the supporting member in contact to only the one end portion.

    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.
