摘要： An image forming apparatus includes an image bearing member, an image forming portion for forming an image on the image bearing member, a contact transferring member for transferring the image formed on the image bearing member onto a transferring medium, a transferring current applying portion for applying a current to the contact transferring member, and a controller for controlling an amount of the current applied by the transferring current applying portion. Images formed on the image bearing member are transferred in a superposed manner onto the transferring medium, which is being conveyed. The controller determines an amount of current to be applied to the contact transferring member based on: the image ratio in the direction perpendicular to the direction in which the transferring medium is conveyed, of an image that has already been transferred on the transferring medium; the image ratio in the direction perpendicular to the direction in which the transferring medium is conveyed, of an image on the image bearing member; and the image ratio in the direction perpendicular to the direction in which the transferring medium is conveyed, of a portion in which the images overlap.

摘要： In a development device which develops an electrostatic image formed on a rotating photosensitive drum by applying a development bias to a development sleeve bearing a two-component developer, the development device includes a specific pattern determination portion which determines whether or not the electrostatic image includes a specific pattern. When the development device develops the specific pattern electrostatic image determined by the specific pattern determination portion, a potential difference between a development sleeve and a first non-image part of a predetermined range which is adjacent to the specific pattern electrostatic image and located on an upstream side in a photosensitive drum rotating direction is set smaller than a potential difference between the development sleeve and a second non-image part which is different from the first non-image part.
