摘要： In an image forming apparatus, a charging process of a photosensitive member is performed by forming a combined surface potential Vd(U+L) by superimposing, on a first charge potential Vd(U) formed on a surface of the photosensitive member by a first corona charger, a second charge potential Vd(L) provided by a second corona charger. The apparatus includes a controller for executing an adjusting operation in which a superimposition start voltage Vg(L)A, which is the second voltage Vg(L) at which formation of the combined surface potential Vd(U+L) is started, is acquired by changing the second voltage Vg(L) applied to a grid electrode of the second corona charger in a state that the first charge potential Vd(U) is formed on the surface of the photosensitive member and in which setting of the second voltage Vg(L) during the charging process is adjusted on the basis of the superimposition start voltage Vg(L).

摘要： An image forming system includes an image forming apparatus including a fixing unit, a folding processing portion, and a pressure-bonding portion. A first recording material having a first basis weight is fixed at a first temperature by the fixing unit and then is pressure-bonded by the pressure-bonding portion after a lapse of a first period. A second recording material having a second basis weight is fixed at a second temperature by the fixing unit and then is pressure-bonded by the pressure-bonding portion after a lapse of a second period. The second basis weight is larger than the first basis weight. The second temperature is higher than the first temperature. The second period is longer than the first period.

摘要： An image forming apparatus has a changing portion configured to change, based on a detection result of a temperature sensor, response sensitivity in starting of power supply by a determination portion based on a detection result of a human body detection sensor in a case where a human body approaches the human body detection sensor. The changing portion increases the sensitivity in a case where a temperature detected by the temperature sensor is a second temperature lower than a first temperature than in a case where the temperature detected by the temperature sensor is the first temperature.

摘要： An image forming apparatus includes a photosensitive member including a photosensitive layer and a protective layer provided outside the photosensitive layer; a charging member configured to electrically charge the photosensitive member; an exposure device configured to expose, to light, the photosensitive member charged by the charging member; a detecting member configured to detect a surface potential of the photosensitive member; and an output portion configured to output information on a lifetime of the photosensitive member. The output portion outputs the information on the basis of an exposure amount with which the photosensitive member charged is exposed to light and a detection result of the surface potentials of the photosensitive member by the detecting member before and after the photosensitive member is exposed to the light with the exposure amount.

摘要： An image forming apparatus includes a rotatable photosensitive member (drum), a first corona charger, a second corona charger, an image forming portion, a voltage applying portion, a surface potential detecting portion, a controller. The controller determines a condition of voltages applied to the first and second corona chargers during image formation, by setting a first voltage condition for the first corona charger so that the surface potential of the drum is a second potential lower in absolute value than the first potential in a state in which the first corona charger operates, and the second corona charger does not operates, and then by setting a second voltage condition for the second corona charger so that the surface potential of the drum is the first potential in a state in which the first corona charger operates under the first voltage condition, and the second corona charger operates.

摘要： An image forming system includes an image forming apparatus, a varnish application apparatus, and a controller. When the image forming apparatus is in a standby state and preheating of varnish in a tank by a heater is completed, if an image forming job of forming a toner image on a first recording material and applying varnish thereto by a varnish coater is received, the controller controls a guide member to guide the first recording material to a first conveyance path. When the image forming apparatus is in a standby state and preheating of varnish in the tank by the heater is not completed, if an image forming job of forming a toner image on a second recording material and not applying varnish thereto by the varnish coater is received, the controller controls the guide member to guide the second recording material to a second conveyance path.
