Electronic device and method for producing the same, image forming method, and image forming apparatus

An electronic device, comprising:

• a support;
• a charge-transporting layer including a charge-transporting material or a dye-sensitizing electrode layer including a sensitizing dye, where the charge-transporting layer or the sensitizing-dye electrode layer is disposed on or above the support;
• a silicone-containing layer disposed on or above the charge-transporting layer or the sensitizing-dye electrode layer;
• and
• a metal oxide film disposed on or above the silicone-containing layer,
• wherein a ratio [Q(ACL)/Q (CTL)] is 10% or greater, where Q(ACL) is a time integral of a transient photocurrent waveform of an electronic device (ACL) measured by a time-of-flight method, and Q(CTL) is a time integral of a transient photocurrent waveform of an electronic device (CTL) measured by a time-of-flight method,
• wherein the electronic device (ACL) has the silicone-containing layer as an outermost layer, and is obtained by removing the metal oxide film from the electronic device,
• wherein the electronic device (CTL) has the charge-transporting layer or the sensitizing-dye electrode layer as an outermost layer, and is obtained by removing the metal oxide film and the silicone-containing layer from the electronic device;
• and
• wherein the silicone-containing layer includes, as a constitutional component, at least one selected from the group consisting of a triphenylamine compound having a hydroxyl group, polymethylphenylsilane, and delafossite oxide.
