摘要： An image forming apparatus includes a toner image forming unit, a nip formation member, a transfer power source, an information acquisition device, and a controller. The information acquisition device acquires specific information that specifies whether a recording sheet as a transfer target of a toner image is an uneven surface sheet having an uneven surface. The controller outputs a bias including a superimposed voltage, in which an alternating current (AC) voltage is superimposed on a direct current (DC) voltage, as a transfer bias from the transfer power source when the specific information acquired by the information acquisition device is not information corresponding to the uneven surface sheet and to output a bias including only the DC voltage as the transfer bias from the transfer power source when the specific information is the information corresponding to the uneven surface sheet.

摘要： An image forming apparatus includes an image bearer, a toner image forming device, a nip forming device, a power source, a controller, and a temperature-and-humidity detector. The toner image forming device forms a toner image on the image bearer. The nip forming device contacts the image bearer to form a transfer nip. The power source outputs a transfer bias, in which an alternating current component is superimposed on a direct current component, to transfer the toner image onto a recording medium interposed in the transfer nip. The temperature-and-humidity detector detects a temperature and humidity. The controller controls the power source to output the transfer bias including the direct current component with a smaller absolute value as at least one of the detected temperature and humidity increases.

摘要： An image forming apparatus includes an image bearer on which a toner image is formed, an intermediate transfer belt onto which the toner image transferred from the image bearer, a secondary transfer member, a guide assembly, and a biasing device. The secondary transfer member meets the intermediate transfer belt to form a secondary transfer nip in which the toner image is transferred from the intermediate transfer belt onto a recording sheet. The guide assembly disposed upstream from the secondary transfer member in a transport direction of the recording sheet guides the recording sheet at a position lower than the secondary transfer nip such that a leading end of the recording sheet contacts the secondary transfer member before entering the secondary transfer nip. The biasing device biases the secondary transfer member to move the secondary transfer member in one of a direction of bias and a vertical direction.

摘要： A transfer device includes a nip forming member to contact a surface of an image bearing member to form a transfer nip therebetween, a pressing device, and a nip pressure changing device. The pressing device includes a plurality of elastic members, to produce a contact pressure between the nip forming member and the image bearing member according to a restoring force of at least one of the elastic members upon deformation of the elastic member. The nip pressure changing device changes an amount of elastic deformation of the elastic member between at least two stages to change a nip pressure of the transfer nip. While the contact pressure is produced by one of the elastic members, the nip pressure changing device changes the amount of elastic deformation of a different elastic member, different from the one that produces the contact pressure, to change the nip pressure of the transfer nip.

摘要： An image forming apparatus includes an image bearer; a toner image forming unit, a transfer unit, a detector, and a controller. The toner image forming unit forms a plurality of types of density detection patterns on the surface of the image bearer in mutually-different positions in a surface-movement direction of the image bearer. The density detection patterns have mutually-different lengths in a direction orthogonal to the surface-movement direction of the image bearer. The transfer unit transfers the density detection patterns onto the surface of the transfer member. The detector detects image densities of the density detection patterns transferred on the surface of the transfer member. The controller calculates an image density difference between the density detection patterns on a basis of a detection result obtained by the detector, and corrects a transfer bias for transferring a toner image on a basis of a value of the image density difference.
