摘要： An image forming apparatus include a latent image bearer, charger, latent image forming unit, developing unit, receiver unit, transfer unit, information acquisition unit, and correction unit. The charger charges the latent image bearer with a predetermined charging potential. The latent image forming unit forms an electrostatic latent image on the latent image bearer. The developing unit develops the electrostatic latent image to form a toner image. The receiver unit receives the toner image from the talent image bearer. The transfer unit applies a predetermined transfer bias to transfer the toner image to the receiver unit. The information acquisition unit acquires residual image generation determination information. When predetermined residual image generation condition is satisfied, a correction unit corrects image forming condition such that surface potential unevenness of the latent image bearer subsequent to transfer is smaller than that generated where predetermined residual image generation condition is not satisfied.

摘要： Provided are an inkjet printing apparatus and a method of controlling an inkjet printing apparatus whereby the performing of a suction discharge operation, for air bubbles that have penetrated inside an ink supply line, can be suppressed to a minimum necessary number of times, and whereby the ink discharge volume that accompanies air bubble suction discharge operations can be kept low. The volume of an air bubble that penetrates into an ink supply line is estimated on the basis of an elapsed time since the last air bubble suction discharge operation, and in addition, the volume of an air bubble that penetrates into the ink supply line during main tank installation is predicted. The suction discharge operation (choke suction operation) for suctioning out and discharging air bubbles is conducted when the sum of these estimated volumes becomes equal to or greater than a predetermined value.
